What is the difference between the H1, H2, H.....................etc??

I'm looking for a kit for my stock headlights/foglights until I can spare the $ for retros.
Thanks

 

stock headlights you need 9007
foglights are h11

 

Thanks

 

the shape of the base of the blub is different. Basically if you do not have the right bulb "size" it cannot fit in your housing.

 

as previously said 9007 is what you'll need for stock headlights, I'd suggest getting the bixenon ones so you can retain the high-beams (you'll need them for inspection if your state still does them), check out vvme and ddmtuning for some nice fairly priced kits.

 

Love my DDM kit in my Speed3. No hassle, no headache. Fair pricing

 

cool story.
