Do 2010 smoked headlights fit a 2006?

yup, direct fitment..

if I were you I'd search for the BHLM

you can make your stock headlights look JUST like that in any color you want..

(1) Welcome to CT! ... :waytogo:

(2) I can't find a parts listing that runs up into the 2010 model year. The exact headlight unit part numbers have mutated a couple of times since the 2005+ generation was introduced. However, I don't find anything indicating different dimensions or fitment on the headlamp assemblies.

... So my best guess is 'yes' - they should fit up.

yea i am tryin to get some for my Xr
