A few years ago I purchased a set of halo projector headlight from ebay. I don't remember the sellers name or the brand of the lights. 1st my park lights stopped working, I checked all the fuses and bulbs and the bulbs and fuses where good. So I didn't worry about it, the side markers on the headlights still worked. Well today my left turn signal stopped working. I thought the bulb was bad, so I changed the bulb and it still hyper flashes as tho the bulb is bad. So I put the suspected bad bulb in the right side and it worked. The side marker lights on both sides still work. My question is, is it the headlights or the wiring of the car? Im not very good with chasing down electrical problems, my patience is very thin. Ive checked the bulbs and fuses, what do I check next? I would hate to order a new set of headlights and still have the same problems, so I would like to find the problem before I shell out some money. Any help will be appreciated .
