do you have xenons? If one of the xenons is out then it's the d2s bulb. Get some off of eBay. I bought some 10000k d2s bulbs and they work great especially for $45 a pair! If you want to stay oem look then get some 6000k d2s. My eBay ones were actually brighter than oem because the oem ones had fogged over.

The H7's are probably the high beams or the fog lights.
