do i need a load resistor for led turn signals

There is no need … Installing a load resistor kit. So in doing some more study, it seems the load balancer is nothing but a resistor package that is wired in to the ground and each turn signal hot lead on the way to the signal light. Long Answer: If you are planning on upgrading your signals to LED’s you will not be able to determine if you are going to need resistors. If you're just replacing your bulbs this should be no issue, but if you're completely replacing your signals and wiring in new ones, be sure to double check the polarity. Look for someplace with some air flow and avoid tucking them into the headlight bucket where they'd be likely to melt the insulation from other wires. Another option is rated at 550 lumens but you'll need to be sure that it will fit. Switching the front turn signal and marker lights to LED will require the addition of resistors and diodes. Slip the quick connect onto the vehicle’s wire first. To add a load resistor to an indicator (turn signal) it has to be wired into each LED light bulb in parallel. Do NOT apply power directly to a bare LED. The change is to ground it to an actual ground and combine both positive signal leads to the same indicator lead. Using a heat-sink clip, or just an alligator clip, on the wires and resistor leads will help protect them from excessive heat. R2 = 8.24 ohms. There are several options available for LED signals. If you're replacing your stock bulbs with LEDs in the same fixtures you simply need to replace the bulbs and move on to the "Fast Blink" section below. Why are installing load resistors necessary for LED turn signal lights? Once you have a good location selected, locate the positive and negative wires. Resistors are not polarized so the direction doesn't matter. You should look for this type of bulb, which throws its light in all directions, and get the brightest that you can find and that will fit your housing. Through the use of a load resistor kit (pictured right), LED bulb blinking can be slowed down to a normal rate. I checked your order and it looks like you bought a total of 4 LED lights, because of that I would recommend you get two sets of Putco LED Light Bulb Load-Resistors # P230004C-2. When you remove the OEM blinker lamps from your motorcycle and install LED blinker lamps, a wide range of problems can occur - such as the fast-blink, no-blink. I am submitting this with the view of clearing up some of the "mystery" that seems to surround the topic of replacing stock incandescent turn signals with LED turn signals, and the associated need for the amazing "load equalizer". When you buy an LED lamp that is ready to use, there will be a resistor already installed. However, this may take away the auto-cancel function of your signals if you have that. Remember, "heat the material, not the solder" to get a good connection. We recommend picking up a pack of resistors if you are … Some people get lucky and the LED bulbs work without a load resistor, mostly because their later model vehicle turn signal ECU is already LED compatible. Theory (3) A flash controller/resistor is necessary for every LED turn signal or light that is installed. Bulbs and kits typically have these built in but remember this if you're building something from scratch. The load resistors trick the truck into thinking the LEDs are bulbs. This one draws 165mA, so let's see what its resistance would be. I have installed the Tail as turn in the rear with no problem but for the front, Im having a hard time finding good 4runner specific instructions. If someone has done a three wire resistor, let me know which wires I need to tap for the LEDs to work properly. The alternator and regulator are made to provide UP TO a certain amount of current at SOMETHING OVER a certain voltage. Page 1 of 2 1 2 Next > Sponsored By: Apr 15, 2013 at ... You need a real harness for it, with the capacitors built in, or you can take your luck with a few of the eBay "hid warning capacitor" things. Connecting a bare LED directly to your motorcycle battery will immediately destroy the LED. LEDs also must have some load (resistor) in series with them. There must be a some load (resistance) in series with the LED or it will immediately burn out. You can use the T taps so you do not have to cut your car's wiring. Cant turn off the halos. You should connect the load resistors between 31 the turn signal switch and Ground, one per turn line (Ch = Chocolate and Dg = Dark Green wires). Short Answer: There is no way of knowing. You can use the T taps so you do not have to cut your car's wiring. If your bike has a single indicator light on the dash for both left and right signals, the resistors can cause that indicator to become a path between the two sides causing all four signals to flash. Next, insert the end of the resistor wire into the quick connect. NOTE! Visit our Disclaimer and Terms of Use page for more information. This resistor is what makes the resistance higher for the LED assembly than that of a bulb. I’ll run you through 4 of my most common that will just about cover any LED turn signal install type you’ll come across. When you're selecting a replacement bulb for your stock signal housing you need to remember that the housing is designed for a bulb which throws light in all directions and makes use of the reflector. They must be connected with the positive termal toward the turn signal power and the negative terminal (indicated by the line around the end representing "-") toward the indicator bulb. One Load Resistor is required for each turn signal bulb. I bought a 2010 Wrangler that the previous owner had installed LED front turn signals on (He said they were professionally installed in a shop). In the case of the Mean Streak the bulb is mounted sideways in the housing, making matters even worse. Amazon and Custom Dynamics offer ready-made resistors, or you can make your own (thanks to BareAssChoppers.com). Yes, you will need a load resistor for each LED bulb you install on a turn signal circuit. I picked up the Diode Dynamics Tail and Turn kit and their HP24 LED Front Turn signal switchbacks w/resistor kit. LEDs don't draw as much current as incandescent bulbs so the truck thinks the bulbs are burnt out. .09 + 7.5 / R2 = 1 As jbrnigan and fritzthecat have mentioned, adding the resistors to the rear turn signals will correct hyper flash after adding the LED front signal/DRL. Connection InstructionsConnect one wire to ground and the other wire to the turn/brake wire. The standard resistor for motorcycle turn signals is a 8 Ohm, 25 Watt resistor which will work on virtually every LED turn signal. That additional power that it's drawing is being dissipated as heat. In other words, we'll effectively short-circuit the LED with the load equalizer. So even with replacing the relay I will need the load resistors when I change out the front marker lights and turn signals? I did some research and it seems that I need a resistor. One source of confusion seems to be the idea that LEDs offer lower resistance to current flow than a typical incandescent bulb. Just find a good spot on the metal to install them where the resistor is not touching wiring or plastic. The best thing about load resistors is that they do not have any positive or negative terminals. See how many questions are asked about load resistors and hyperflashing aftermarket LED turn signals. Q: I am trying to hard wire a single white led light that's powered by 3 AAA Batteries to my vehicle. Just remember that LEDs are polarized, meaning that they won't work if you mix up the positive and negative connections. According to the schematic to the right (from the Mean Streak service manual), the negative wire is black/yellow and the positive is green (right) and grey (left). In those cases, it's not because of any resistor built into the LED, it's just the LED compatible flasher unit. 7.5 / 82 + 7.5 / R2 = 1 It always needs a resistor in series or some other current limiting device. So what resistor would I need to drop from my vehicle 12 v to 13 v to 4.5 v A: If you enter thes Therefore, it becomes easy to include them in the circuit. Some LED bulbs found in auto supply stores are highly directional and not well-suited for this purpose. The turn signals will only use what they use. An excess of voltage can damage either incandescent or LED bulbs. If your're building your own lamps from component parts you have to add the resistor yourself. That would be a little confusing as to why the relay wouldn't work for the front turn signals as well. The stock bulb is on the left. The resistors must be able to handle virtually the entire load, so get resistors that are rated for 50 watts or more. Completed pic with DRL and halos on at night. LED Load Resistor for the turn signals Discussion in 'Exterior' started by BlownGP, Apr 15, 2013. Remember that the goal is to pull around 25 watts per bulb and the LEDs are drawing very little of that. Brought to you by http://www.iJDMTOY.comOne pair of 6 Ohm 50W LED Load Resistors for LED Turn Signal Light Fix or LED License Plate Lights Error Fix.http://store.ijdmtoy.com/LED-Turn-Signal-Light-Rapid-Blink-Fix-Equalizers-p/aa1037.htmThese 6 Ohm, 50 Watt LED load resistors will work on any vehicle and can be connected across the turn signal bulbs or License Plate Lights to simulate the load of a regular filament bulb (2 Amp load). This will solve LED related turn signal lights or license plate light problems such as hyper flashing, no flashing or burnt out bulb indications. This is completely true when talking about bare LEDs; they show virtually no resistance when measured. LED DRL Resistors installed using the provided self tapping screws. R1 = 7.67 ohms. Mounting LED turn signals to the front of your motorcycle: I use a large variation of LED Headlight sizes and shapes on my custom motorcycles. LED Turn Signals May Need Resistors If you are replacing front and rear turn signal bulbs to LED, be aware that many vehicles use a flasher unit that is designed to work with incandescent bulbs. CUTEQUEEN TRADING 4PCS 50W 6Ohm LED Load Resistors for LED Turn Signal Lights or LED License Plate Lights or DRL (Fix Hyper Flash, Warning Cancellor) with 8pc Quick wire Clip 4.4 out of 5 stars 984 $6.99 $ 6 . (An interesting thing about incandescent bulbs... 1) they're not polarized and will work with current flowing in either direction; and 2) they have very low resistance such that a bulb can serve as a ground connection for another circuit.). There is no concern about which end of the resistor is connected to power, and which to ground. An alternative to using load resistors: an LED compatible turn signal flasher * The current through the circuit is constant so I LED is also the current through the resistor. The above calculation returns 9.15 ohms, only a couple of ohms different. Do I Need a Resistor for my Bike? However I noticed that the turn signals don't work while the front headlights are on. The easiest option (if not the cheapest) might be to get an LED flasher for your bike. Do NOT apply power directly to a bare LED. One of the most common problems that arises when replacing stock filament bulbs with LED bulbs in most vehicles is hyper flashing or bulb out warnings. There must be a some load (resistance) in series with the LED or it will immediately burn out. Again starting with R = E / I: So, from the flasher's perspective we need to make it see about 7-2/3 ohms instead of the 82 ohms of the LED. Unlike plug-and-play LED flasher modules, load resistor kits require some wiring to install. 1. High current draw = low resistance (Incandescent). If you check online for load-equalizers you'll find them varying from about 6 ohms to 8 ohms, and any of these will work. If you're replacing the fixtures you'll need to cut and solder wires. An issue may arise when the incandescents are replaced with LEDs: the turn signal lights flash too rapidly, a condition known as “hyperflashing”. I.e. LEDs also draw far less power than incandescent bulbs but remember, they only draw any power at all when they're on and, as you'll see later, you'll need to add resisters to effectively increase the power consumption back to that of incandescent bulbs anyway (if you want to avoid the fast-blink or "hyperflash"). 7.5 = 0.91R2 A load resistor is required for each LED light bulb in the turn signal circuit, (you may only want to upgrade the rear of the vehicle? Otherwise find some in the 6 - 8 ohm range, around 50 watts, and just keep on reading... A little care must be given when installing the load equalizers since they can get hot. I have check with my meter and I am getting 4.5v to the led. You can also use a frame ground in place of connecting to a negative wire, as long as you locate a good ground point. To fix this problem you need to add a pair of diodes into the circuit to ensure that current can't flow the wrong way through the indicator lamp. If you are trying to replace an existing incandescent bulb with LEDs, you definitely need a resistor. LED (light-emitting diode) turn signals offer several advantages over incandescent, not the least of which are reliability and long life. A nice place on the Mean Streak is right next to the battery, where it's also easy to tap into the rear signal wires and the frame serves as a heat sink. If you're experiencing "hyper flash" where the signals blink real fast you'll need to add load resistors as mentioned above. A good explanation of Ohm's Law, with a focus on resistors for LEDs, can be found here and here. This warning should only apply if you are building your own signals. I want to swap to LED front turn signals but the issue is if I need resistors or not? With that information we look at your LED bulb. Total resistance becomes ( 1 / R1 + 1 / R2 )-1, so to find the resistance that we need to add: 1 / 82 + 1 / R2 = 1 / 7.5 (rounding a little) The load resistor goes across the light bulb connections, between the supply and ground. The resistor can be installed in either direction. If you don't install load resistors (also known as equalizers) with LED turn signal bulbs, you will experience the notorious hyper flash issue. The new LED is on the right ~5' away from the wall. The Custom LED Universal Load Equalizers come in a few sizes, and fix the common problems associated with retrofitting incandescent turn signal bulbs to LEDs. So I can do away with the Batteries. Light grill mount (Example) Installation of rear turn signals requires 2 flash controllers/resistors. A standard incandescent bulb is typically rated for around 25 watts at 13.8 volts DC. For incandescent bulbs it doesn't matter. I have resistors on the rear turn signals already. Note that diodes are polarized, unlike the resistors, and won't work properly if they're installed backwards. This diagram shows the installation of the diode kit from SuperBrightLEDs. Hyper flash is exactly what it sounds like, where the turn signal light flashes rapidly and is almost headache inducing. LEDs are directional, meaning the positive and negative connections must be made properly. Once you get your new LEDs installed you'll quickly find that your signals blink far faster than normal. 99 Load resistors are resistors that are put between the positive wire and negative wire of the LED turn signal wiring, bridging the two wires together raising the load (hence load resistors) for the entire circuit. Strip off a bit of insulation from each wire and solder one lead of the resistor to the positive and one to the negative, for each signal. In this diagram the stock setup has the indicator bulb grounded through the other signal circuit. To prevent hyper flashing of the LED turn signals, you will have to add load resistors to the circuit. LED Signal unit designs vary. If there is extra current available from the alternator (and battery) the turn signals are not changed in any way. So there are a few different ways to go about this. You could put them in a battery or junction box though. Maintenance Tips for Vulcans and Other Motorcycles, Copyright © 2015 - 2020 Gadget's Fixit Page. If you purchased a "load equalizer kit", or built your own from BareAssChoppers, then you've already added diodes and this issue should be fixed. Installation of front and rear requires 4 flash controllers/resistors. If you get a bare LED and connect it to a battery you will burn it out. If you want to figure out exactly what you need, check out the next page (Scary algebra warning). One LED resistor is required for each turn signal bulb or each license plate light bulb. You will need load resistors that draw 50-watt power and have a resistance of 6 Ohms. For more detail, please check Install LED Load Resistors.Note: LED Load Resistor will get hot, therefore, please don't mount the LED load resistors on plastic. Remarkably, even if the calculation is changed to include both front and rear signals, the result changes very little. For this reason, unless you're dealing with very low voltage, you cannot use a bare LED in your application and must add a resistor in series with it. You would need one per affected circuit. As an Amazon associate, commissions may be earned by this site from Amazon links herein. The other fix for this is a pair of load-equalizing resistors that will shunt current to ground, making the resistance and power draw seem normal to the flasher. Applying Ohm's Law to find the resistance, we first determine the current draw in amps: Now solve for the resistance of the bulb: R1 = E / I https://superbrightleds.com is a recommended vendor for bright LEDs, but this one is not suitable for use in a motorcycle turn signal housing. I find that the LED lighting uses a lot less electricity than the stock incandescent bulbs. Corrects hyper flashing and bulb-out warning caused by LED replacement bulbs This is a feature of your flasher designed to let you know when a bulb is burned out, which is exactly how the flasher sees the LED due to its much higher resistance. Load resistors increase the amperage draw on a circuit. You may have heard the term "Load Equalizer" or "Load Resistor" being thrown around when looking for a solution to your fast-blink or no-blink issues on your motorcycle. Theory (4) Installation of LED signals with built in flash controllers/resistors do not require additional flash controllers/resistors. This article will assume that you're looking for the simplest approach and will replace only the bulb. The output of an incandescent bulb is around 400 lumens while the bulb at the left puts out 220 lumens. The component resistors found at Radio Shack and the like are usually rated in fractions of watts and are completely inadequate. Eliminate Hyperflash & Dash Warnings The optional SYLVANIA load equalizer can be used to eliminate the hyper flash (higher frequency turn signal) caused by LED replacement bulbs in some vehicles. If you're just replacing your bulbs this should be no issue, but if you're completely replacing your signals and wiring in new ones, be sure to double check the polarity. 7.5 / 0.91 = R2 Connect one wire to ground and the other wire to the turn/brake wire. Incandescent bulbs can burn out or break at the most inopportune times and LED bulbs are virtually immune to these issues. 7.5 / R2 = 0.91 You can replace your stock 1156- or 1157-type bulbs with similar bulbs, you could add run-turn-brake functionality with something from Custom Dynamics, or you could replace the entire assembly for a completely new look. The way to reduce the overall resistance of a circuit is to add another load in parallel with the primary load, so we'll put a load equalizer in parallel with the LED.
