Hey, i replaced my factory bulbs with the hid-matched ones from RPM, very satisfied, but last week my left headlight went out. So i took it out and it didnt appear to be burnt out. I put the stock bulb back in...that didnt work. hmm...so i put my lights on while installing the xtech one again...and as im putting it in, it turns on!!...then off....on....then off....so i get it all clipped in....and its off...wont come on....jiggle it....maybe....has anyone had this problem b4? btw ive already checked all the headlamp fuses and their ok!....im thinking i might have to take the bumper off and take out the headlight section to get a good look at the connections.....any advice? falcon?
