Yes Osram Night Breakers are far better than standard halogen even though they are a standard bulb if you get what I mean.
There’s been talk of LED bulbs amongst others being mot fail, remember that the new mot regs have come from EU so will be EU wide too.
I have found the round headlamp terrano to have poor lighting but the later style lamps are far better. As said get some decent auxiliary lights to supplement your high beam.
