Headlight bulb sizes and question.

[Taylor-34]

Idk if it belongs here or in the DIY section.

2011 silverado 2500

Anyway, I want to swap out for HIDs:

Are the low beams H11s?

Whats the difference between H11 base and 9005 because I have a brand new 9005 kit if they worked.

Reason I'm asking now is it's such a pain pulling the lights out, so I wanted to have the right ones before I did the swap.

Also, what are the marker light bulbs?

Thanks.

Do an image search of both H11 and 9005 you will see the differences. I sell both of those at work frequently. As far as the marker bulbs, I can not tell you off hand.
