headlight size

[lowNslo]

Hey guys i tried to search and couldn't come up with much. I bought the wife a yukon 07 model and we are ordering the drop and cat back hopefully tomorrow and getting the hid's orderd as well. I haven't pulled the headlight assmbly out to see the bulb size simply because its raining its ass off. I have read that h11 is the replacement but the h13 is the hid size for replacement. Can someone help me with the correct size so i don't screw up my order!!!!

The headlight bulbs are H13 but depending on if you are wanting to still have high beams that model number should be slightly different, like H13-2 or similar.

The H11 reference may have been for fogs and/or reverse applications...

So if i order hid's what size should i tell the guy? H11? Will I lose my high beams? just not sure what i wan't to do.
Thanks

You want H13, not H11.
