Same here, upgraded to nightbreaker plus bulbs.
On the plus side, they're now a nicer shade of white. On the negative, the dipped beam is still terrible. the full beam isn't too bad though, but it's having the chance to actually use it which is rare around here.
I thought at first it might just be my headlights need realigning but pulling up close to a wall shows they're fine. As said by others they don't particularly light the side of the road well. Also when you've got other cars coming towards you, the low driving position of the Mini + other people's bulbs means you can barely see where yours are pointed.
Was tempted to look into running 80/100s, appreciate they're illegal but given the amount of people driving other cars with full beams constantly on I'm starting not to care.
