I have an 04' coupe and I was switching out my bulbs with LEDs and tonight when i turned on my lights my right light was out but when i turned them off then on again it was fine. does anybody have a pic of what I might be looking for or can lead me to what LED and Headlight bulbs I need? Im looking to put amber LEDs in my parking(Clearance strip) and my front side marker. And Im guessing I have HIDs already in my G If I just want to upgrade do I need to buy all whole new set or can I just use my old ballasts and just buy 6000k bulbs???
any help would be great!

 

If you already have HID's (I believe all US G35 coupes had HID's), then you can just replace the bulb with a 6000K, no need for new ballasts.
