They will only work for the high beams (H7) on '05/'06 cars. The low beams on '05/'06 are H1. For model years '07 and above (new style headlights), both high and low beams are H7.I have an '06. Anyone know if this is compatible with an '06 car? I'll go grab my manual and check but I have a hard time finding things in that manual.
