Xenons on all the time The Bi-Xenons are basically xenons that are on all the time. A flap/visor comes down during low beam to dim/restrict the bulb. When you turn on the high beams, the flapper retracts and you get full beam = high beam. The other lights (halogen) only come on when there is a problem with the Xenons or when you want to flash and the Xenons aren't warmed up yet. I only know this because I had far too many headlight issues that caused me to know more than I ever wanted. |
