Over the Black Friday sale at 914 rubber I ordered their LED headlight kit and some LED gauge bulbs for the teener. Got those all installed over the weekend and all is working with the exception of hi-beams.
The driver side will turn on the hi-beam when the switch is pulled, but the passenger side goes completely dark and the indicator in the tachometer does not light up either. It did all work okay prior to LEDs so do I need to put a resistor inline somewhere? I emailed Scott over the weekend but haven't heard back yet so I am guessing they are keeping busy, thought I would come to you fine folks for some advise. Cheers! |

Each headlight has its own fuse for high and low beams. Look there first.

Check the wire orientation in the headlight connector. Had the same issue and found 2 of the wire were swapped on one side. System still worked fine with conventional bulbs but with LEDs one of the highs wouldnt activate until corrected.

That was my first thought! LEDs are "directional", and if you mix up the power and ground connections they won't light up at all. Unlike incandescent bulbs, which only care that current is flowing through them and not which direction.

Appreciate the suggestions, hadn't even thought of the wiring being backwards. Will double check that they are the same side to side since I have one side that works with hi and low beams I can compare against.
Fuses are a good place to check too. |
