Guys,

I am thinking to replace my stock fog lights to match the HID. My car is 2004 A4 and from what I searched the size of the fog light bulb should be H11. But on some web sites also indicated as H1. Are H11 and H1 the same bulb? What bulb should I purchase for my car?

Thanks for your reply.

 

no H1s are really small and H11s are huge they headlight bulbs
u gotta get H11s

 

Thanks Panda.
