how to install load resistors for led headlights

If you have recently installed LED headlights on your car, you may have noticed that the turn signal lights blink too quickly or do not work at all. This is because LED headlights use less energy than halogen headlights, causing the car's turn signal relay to blink rapidly. The solution to this problem is to install load resistors that balance the energy consumption and prevent the turn signal relay from blinking too fast or malfunctioning. In this article, we will guide you through the simple process of installing load resistors for LED headlights.

Select the load resistors

Before selecting the load resistors, you need to determine the wattage of your car's turn signal lights, which can be found in the car manual or by contacting the manufacturer. Once you have the wattage, you need to choose load resistors with a wattage rating that matches or exceeds that of the car's turn signal lights. Most LED manufacturers sell load resistors that are compatible with their products, so it is advisable to purchase from the same manufacturer to ensure compatibility.

Locate the turn signal wiring

The turn signal wiring can be found behind the headlight assembly or under the car's dashboard. Use a multimeter to determine which wire corresponds to the turn signal lights. Set the multimeter to the continuity mode and touch the probes to the wires until you hear a beep. This will indicate that the wire is connected and is the turn signal wire. Alternatively, you can refer to the car's wiring diagram to locate the turn signal wire.

Install the load resistors

Once you have located the turn signal wire, you can now install the load resistors. The load resistors can be connected in parallel with the turn signal wire. Cut the turn signal wire and connect the load resistor using wire connectors. Make sure to connect the load resistor correctly by following the instructions provided by the manufacturer. The load resistor should be mounted on a metal surface to dissipate heat and prevent overheating.

Test the turn signal lights

After the load resistors are installed, it is important to test the turn signal lights to ensure that they are functioning properly. Turn on the car's ignition and activate the turn signal lights. The lights should blink at a standard rate and should not blink too fast or too slow. If the blinker rate is still fast or the lights do not blink, check the wiring connection and make sure the load resistor is installed correctly.

Conclusion

Installing load resistors for LED headlights is a simple and cost-effective solution to prevent turn signal lights from malfunctioning. By following these easy steps, you can have efficient and properly functioning turn signal lights in no time. Remember to purchase load resistors that are compatible with your LED headlights, and be mindful of your car's wattage rating. With proper installation and testing, you can rest assured that your car's turn signals will work perfectly.
