Cheers Kev. Do they also bend right on to oncoming traffic or are xenons only useful for going round left bends? (Serious question by the way)
I know it is illegal not to have washers with xenons, but why? What function do they provide its not as if the washers come on automatically to clear the headlamps. It seems strange that the law insists you have an option with them but that option doesn't have to be used.
Yeah, if your going round a roundabout, esp one of those big jobbies it will move to always give you the best/full view of the road ahead. I went out one night and had a right good play around with them, they are pretty clever.
This is a guess by the way, but I'm assuming there is some sort of sensor that will detect how much the wheel has turned and for how long then send a signal to the lights to compensate for the amount of turn that you have done, and for up and down I assume some sort of balance is in place to tilt or raise for how much the balance has been adjusted then send the signal again to the lights.
It must have a slight time delay because if you go over a hump on the road the lights dont go nuts (up and down) if you know what I mean, and if you zip through a roundabout and take a quick first exit you can be too fast for them.
