I have two PIAA driving lights. had em wired in a while ago, worked fine for like 2 years, then they stopped working. the switch turns on, the relay turns on, but the lights don't. i have driven through mud/water alot, so could that have f'd up the connectors and the wiring leading up to the relay? cause there is a noticable amount of dirt everywhere, so could that be the problem? if anyone has some ideas, i'm all ears
