LED Corner Lights Won't Come on with Load Resistor Installed

Question:

I put in led bulbs for my turn signals. Led bulb acts as turn signal and corner light. So there are 3 wires, 1 for turn, 1 for corner and ground. I installed a resister to eliminate the hyper flash and that works great but now my corner light will not come on. Any suggestions?

Expert Reply:

Load resistors are used on LED vehicle lights to prevent hyperflashing on turn signals. Make sure you only have the load resistor installed on the turn signal wires as they are the only lights that will be flashing. I attached a useful diagram to reference while making sure your load resistor is installed correctly.

Additionally, you could have a loose or weak ground connection. Clean the area near your ground connection to remove any corrosion and replace any corroded ground screws. It's possible that the ground isn't strong enough for the corner light but is strong enough for the turn signals which don't require as much power draw.

If your wiring is correct, test the corner light wire with a circuit tester such as # PTW2979 to test if it is getting power when it should.
