"Auto" headlights
Someone told me this and I was wondering if anyone knows whether this is true.
Is it bad to keep the headlights switch on "Auto" at all times? Is there any reason not to? I have Bi-Xenon's and someone told me its bad to keep it on auto because it makes it easier for the headlights to burn out. Does anyone know if this is true?

thanks a lot guys! thats exactly what i thought.
But your answers lead me to another question... aren't the daytime running lights halogen since its hte smaller yellow inner lights that are on for daytime running lights? i was under the impression that the bi-xenon's are only the two big lights on the outside.

Leave them on AUTO. The car will detect and decide whether to turn your lights on or off based on the conditions outside and its pretty damn good at it.
As for the reply about tunnels .. you're supposed to turn your headlights on when you enter a tunnel, and off when you exit. The car has been designed PERFECTLY.

I thought the inner lights also functioned as a "flash" of high beam light when the stalk is pulled back (to signaling while passing, for instance) while the BIX headlights are off. Since xenon lights lag a bit on take-off, they don't respond immediately when needed as a signal.
