If you do a search there has been many posts discussing the + & - points of fitting Xenons.
I've done that, there's nothing on this adapter lead.
also you need headlamp washers, hopefully you have them already, otherwise again an MOT failure and therefore illegal.
It would be if I was manufacturing cars but as it's an aftermarket accessory that law doesn't apply as long as they're "E" marked as these are. MOT will only check the brightness and aim. OEM xenons are a standard 35W. Unless I have Jabba the Hutt in the boot when it's MOT'd the aim will be the same as the standard halide light.
They possibly fit on the rear axel sensor as the Xenon’s have a self leveling system! If the self leveling is not fitted along with the washer jets then you will be driving illegally, this will mean void insurance and the car may fail its MOT.
As above.... No it's not part of the self leveling, that's a different harness again.
Anyone actually fitted this?
