Installation Guide: LED Load Resistors

B6LR12/2 & B6LR24/2

WARNING: Load Resistors are designed to get HOT! DO NOT Install on/near painted surfaces or plastic!

A load resistor is generally required for each filament bulb that you are replacing with LED’s. To add a load resistor to an indicator (turn signal) it will need to be wired into each circuit in parallel.
I.e. The load resistor goes across the connections, between the supply and ground. 


  • Any installation is at your own risk. Each vehicle may be different, or may have been previously modified.
  • It is good practice to disconnect the battery, when wiring vehicles.
  • If you’re unsure, use a qualified auto electrician. As modern vehicles electronics can be damaged easily.

Single Function Circuits:
Using the diagram below, you want to splice the Load Resistor’s wires in so that it connects ACROSS the positive and 
negative wires of the vehicle’s wiring. The Load Resistor is specifically designed to represent the same power-draw as a standard filament bulb so that the vehicle does not mistake the lower power draw of an LED bulb as a bulb that is burnt out or missing. DO NOT allow the Load Resistor to touch any wiring, it gets very hot under normal operation.
