Gilly;

Just FYI - there is a relay that cuts out the halogen "flash to pass" high beam when your xenon headlights are on and you either pull the lever for flash to pass, or flick the lever forward for high beams. In those cases you get the xenon highs only.

What I did was open the light assembly and bypass the relay, so I get all four lights (xenon wide open on high plus halogen H7's) when I have the headlights switched on. This works for both flash to pass and for steady high beam on. It's absolutely awesome. I have light 300 to 400 yards down the road, great peripheral coverage across both shoulders of the road, and outstanding definition of objects in the distance. The job took about 15 minutes per light to cut & splice the wiring.

My wife calls them my "100 megaton" lights! I have to be extremely aware of oncoming traffic or when following at a distance, but when on the road by myself it's perfect for seeing those "buck in rut" deer cluttering our highways in Wisconsin in the fall when coming home from work after dark.
