How to Wire a Turn Signal Resistor

A turn signal resistor is a vital component for installing LED turn signals on your vehicle. Not only does it prevent the hyper flashing that occurs when replacing conventional bulbs with LED ones, but it also helps your new lights work more efficiently and effectively than they otherwise would.

The process of wiring a turn signal resistor isn’t complicated, but it’s important to do it properly. This will ensure that your new LED turn signals are as efficient as possible, so you don’t waste power and heat in the long run.

First, make sure that you are using the correct wattage for your LED turn signal bulbs. If you aren’t familiar with the wattage of your LED bulbs, it’s best to consult your owner’s manual or an existing incandescent bulb to get an idea of the wattage needed for your vehicle’s lights.

Once you’ve determined the correct wattage, it’s time to wire your LED turn signal resistors. There are many different types of load resistors, so be sure to select one that is suited to your specific LED turn signal bulb model.

Typically, load resistors come in six-inch lengths for easier installation and have a rating of 50 watts, 6 ohms. This is usually enough to compensate for one bulb, but if you’re changing multiple bulbs, you’ll want to use more than one resistor.

Installing the Load Resistor

To begin, you’ll need to tap the load resistor into each LED light bulb socket in parallel. This means you’ll need to tap the positive and negative power wires from each LED bulb socket to the resistor’s two pins. You can find these pins on the underside of each socket.

Next, you’ll need to mount the resistor to a metal surface on your vehicle. This will help dissipate the heat that your LED turn signal resistor generates as it’s used, avoiding potential damage from high temperatures and preventing overheating.

You should mount your resistor to a metal surface that is away from other wires or plastic parts on your vehicle, so that you can minimize potential damage from overheating. Once you’ve finished, test your turn signal to make sure that it’s working as expected.

The wattage of the resistor should match that of your LED turn signal bulb models, but be sure to check with your supplier for the exact wattage.

If you’re unsure about what wattage to use, you can perform a quick and easy test to see if the resistance is correct by activating your turn signal for five minutes. If it’s too hot, you should use some burn salve on the resistor to cool it down.

If you’re still having trouble with your LED turn signal resistors, you may need to connect the resistors into a circuit that is not already used for LED lights, such as the brake light circuit on your vehicle. This is a simple and safe procedure that will prevent overheating and damage to the load equalizer.
