Hahaha, I bet that was a killer. I love Xenon headlights, but too many people flash their high-beams as if you are using your high-beams and they want you to turn them off. The trick to Xenons is to not look directly at them...if you look right at them, there is an eye-raping glare, but if you just drive, they shouldn't bother you too much. My only problem with Xenons is if the car is coming at you at an angle, then the glare is absolutely killer, and it seems like the auto-leveling feature is worthless.
One car that should not have Xenon headlights is the new Range Rover....it is simply too high off the ground to have Xenon headlights and it just always creates massive glare for other drivers. Hopefully, they will find a way to correct that issue, and if you'll notice, the Lexus GX470 and LX470 (both great luxury SUV's) do not have Xenon headlights available simply for that reason. I wonder how Land Rover got away with it.
