is the tl-s headlight unit a direct fit into a 2004 TL? if so where can i find them? can i buy them from a dealer, and whats the avg cost

 

nope, it requires some wire changes. Also the balast was changed in 06 so it might affect fitment.

 

yea, it might bolt on... but it wont plug in... and yea, 04 had different ballasts, but i dont think are too large in size difference...

wiring, completely different.... but hey, everybody said the 07 TLS mirrors wouldnt fit.. and they do.....

 

Will they fit on an 06 TL?
