I smashed my old electrical adapter on a rock while rock crawling and replaced it with an aftermarket Hopkins one. The lights now work a little odd. With my vehicle lights off, everything is normal and works fine. Brakes, Hazards, left and right signals. With my vehicle lights on, everything EXCEPT the left turn signal (and left signal with hazards) works. Now since that light works with my vehicle lights off, it is obviously not the bulb. I'm not sure how this could have happened though.
