Do not use bi-xenon on PFL car only if it would be from factory! I was thinking as well to put in bixenon for high beam as well! It takes 10secs to work normally for xenon beam....and if u r switching xenon block ON and OFF so often...it is not normal! I was thinking to code fog lights for turns to get ON fog light when car is turning! I built in xenon in fog lights and changed my mind! It is very beautiful now when fog lights and lower beam are the xenon and same colour! I am using 6000K! Thinking may be to put in 8000K or 10000K! I have bixenon for lower beam and fog lights we can call it like that!
