I just drove my Jaguar XJ6L (X330) 2326 mile with these installed to Mexico as far as Puerto Nuevo (33 miles past Tijuana on Mexico's Federal Highway 1D) and back. They were far better than any Halogen lights ever were.Unlike the 90's version Lincoln, doesn't the whole headlamp nit need to come out to put a new bulb in?? I recall doing one in an 08 had and it was a pain just to swap a bulb. I did put upgraded bulbs in my 05 though, well, had them put in, and they light up better at night too. Might have to try these though.
They're worth the effort.
