I've had these ones before in reflector headlamps and they have always been a 100% improvement and never any problem passing MOTs or anything. I think all this talk of them being illegal is a lot of hot air as this isn't something that is enforced.

4300k are completely white and dont have a "aftermarket Xenon" look about them.

Am going to fit them after I've done the brakes and hopefully take some piccies of the install too.
