I spend a significant amount of time on the A1(M) at night between Essex and Yorkshire and the lights are brilliant. The only time I've dazzled someone was a lorry driver who's lights were hidden by the armco and the car didn't recognise there was something (a lorry) there.
Aside from that, they have worked superbly. I especially love when you approach a car in front and the beam splits left and right around the car in front.
