I've got the Xenon's with Adaptives too. Had to close my garage door with the lights on and barely turn the steering wheel to prove to myself that I have them. I do. I've noticed some change in the lights from in town to highway, but thought, at first, it was my imagination. As for having the fog lights on with the high beams.....I think that this is not allowed in the USA. Mine won't work. Have to check that out again. I do get cussed with my rear fogs though. They are bright.

 

Yep the DOT does not allow both high beams and fogs on as high beams are considered two sets of lights on an DOT states that there can no more than two sets of lights on at one time.
