Hi,

I would like to change my fog light bulbs, and get some piaa bulbs, anyone know what size our c-class uses? thanx

9006 55W bulbs for fogs
I recommend www.supremepowerparts.com for bulbs. They sell PIAA, but also have their own line of SPP bulbs that are just as good as PIAA for a fraction of the price.
