I've had my retro for over a year now with no problems. until last week when the passenger side headlight flickered when i went over a speed bump. then two days later it would go off for couple seconds, and turn back on then off for good. so i popped the hood and checked all the fuses which were all good. but this part that i hooked up the harness to. right between the red and black wire it lights up. when that lights up the bulbs goes off. so when i move it a certain way it stays on so i'm guessing something inside that things isn't touching correctly. blah
