So i decided to swap out my old incandescence head light bulbs For led ones in my 2011 frontier. Before i made the change i added an 120watt led light bar to my grille. This light bar is powered directly from the battery, on a relay that is controlled from the high beam wire i spliced into from the left headlight assy. That wire i spliced into acts as a ground when my DRLs are on (Because polarity becomes reversed for say time lights) so i put a diode (1N4004) in series with the relays coil So that the coil of the relay wouldnt activate when the DRLs are on, only when the high beams are on. My leds head lights i got are meant for my truck and say “non polarity” on them. So basically there supposed to work as DRLs. Now the problem is ever since i swapped the new led bulbs in i noticed only the left on is working as a DRL but both are working for high/low. My theory is the light bars relay is giving continuity to ground so its by passing the right head light. One time i opened the door and all the interior lights started going crazy. My question for you guys is what type of diode should i use? Would that fix the problem? And do you think my bcm had taken any damage from this flashing moment? Here are the schematics below. Thanks!
