again sorry never fitted any to our crossfire, but bought a set for my crossfire and my Jag Stype, i fitted them to the jag bought some of the ceramic bulb holders as well they worked great very bright, got plenty of flashes from other drivers even on low beam because they are very bright, they were in about 6 weeks when i took car for MOT he failed it due to bulbs brightness, I though swap them for standard and then put back after MOT ( not great has a real ***** of a job) when i cam to do this both lots of wiring including the holders connect to to the ceramic holders had melted quite bad, cost £145 to sort and then another £70 for the Night breakers (Which in my oppinion are a little dissapointing) so therefore obviously never fitted them to the crossfire.
so to sum up i wouldnt bother fella
