Headlight wiring issue

Postby Buckner99 » Fri Oct 09, 2020 8:11 am

1984 Nissan 720 pickup. I bought an aftermarket set of LED Headlights that have both a low and high beam setting. H4 plug and plays, I plugged them into my plugs. Low beams come on, but on the high beam setting in the light. When I flip to my high beams, high beams come on as high beams but low beams shut off.. stock ones would stay on with the highs. Someone told me to wire in a relay on both sides to where all 4 of my headlights will be on the low beam setting when I turn my lights on, and when I flip to my high beams they will all be on the high beam setting. I just don’t know which wires to tap into. Any help would be greatly appreciated. Thank you.
