Headlight ??

[Trav-O]

Is there a difference in wiring and/or header panel with the 08-10 Recessed (XL) Headlights versus the Flush (Premium XL, XLT, Lariat exc.) Headlights?

 

[yeehaw]

The standard headlights on a xl are 6054s and the one piece headlights use a 9008 bulb

In the slow duramax

Yes they are diffferent, youll need to either make a harness or buy one for the main light

 

[Trav-O]

So the Header Panel is the same then?

 

[Spatel23]

yes.
The XL one has two top mount holes for the light versus the one hole on the XLT+ versions but it doesnt effect mounting.

You may want to check with Dustin though, he has both trucks so he can do a direct comparison
