@Derek, sorry about that.....
Can't think of anything that could help you.... (except stop flashinh those high-beams

)
I am wondering if the light sensor (the thingy that puts on the lights when entering tunnels) could damage the xenon's. If there's a thing that xenon hate it's powering on and off all the time. In fact, powering on a xenon when i't's still hot could cause severe damage to the lamp. I wonder if the light sensors behaviour is altered when the setting "XENON PRESENT" is set to "Yes"......
Otherwise it would be wise not to use the "Auto" setting when there are aftermarket xenons present.
