I put SilverStar H7's in mine last night. Replaced the fog lamps with SilverStar 9006's too. The stock wiring for all the lamps looks very small. I didn't have a wire guage handy to check the size to look up how much current that particular wire size is rated to handle. I would be very cautious about going with a higher watt bulb until I knew exactly the gauge of the factory wiring.
