Right, update
Been to good old Alfreds - the Xenon ones are BOGOF at the moment, so scored some replacements. I also got some 100W main beam bulbs on the basis that they won't be on long enough to scorch the reflectors and I won't get tugged for having too bright lights as they're only on when there's nobody else about
It's a pretty big improvement - the weather up here is total shit at the moment, I really couldn't see a thing earlier!
I'm on the hunt for some brand spanker headlamp units as well but they must be the Carello ones!
Cheers!
Neil.
