| Derek, I am sure you could upgrade the highbeam to xenon. But flashing the beam would be impossible since it takes 20 secs for the bulb to fire up.
Bixenon uses a little mirror (or flap) to adjust the dipped beam to high beam when flashing with the xenon on. And most of them use a standard bulb to flash highbeam when the xenons are off.
So you could put xenons in the highbeam, but you won't be able to flash the highbeams. |
