Thanks for the info.
If the main beam is twin filament, doesn't it mean that one of the filaments won't illuminate?
I don't know whether a twin filament bulb needs both filaments powered to give main beam (i.e. the two together provide the necessary lighting power), but if it doesn't, as long as the main beam filament is powered then won't it be ok?
Knew this wasn't as easy as I first thought!
Any suggestions for the H3 bulb then?
(Also, which one is the H3, dip or main?)
