I was given a set of HID fogs. I looked up on sylvannia's website that the 09 mustang takes H11 bulbs in the fog lights. Well the HID bulb says its an H11 but it doesnt have the flange required to twist lock into place on the light. The bulb I pulled out of my fog had H10 printed on it. So which bulb is it H11 or H10. Here is a pic of the HID bulb Im trying to install.

 

You need H10 for a Mustang GT. The H11 is for a V6.

Edit: By the way, Sylvania's site lists 9145 and H11. FYI...9145 is H10.

 

Ok thanks.

 

9145 equals H10

btw headlights are H13

 

Thanks. Are our OEM HIDs 35 watt or 55 watt? And what is the color temp of the OEM HIDs? I want the curtains to match the drapes.
