Having had my fill of near death brought about by the lacklustre bulb I got a 12v 35/35w halogen to replace it. Fitted it myself and everything ( for context, I'm the kind of bloke who can end up with spare screws and bits if I try anything mechanical). But now I'm having panic attacks that I've fitted it wrong - I did a scientific test called standing in front of the bike and looking at the headlight - it appeared more dazzling on dip than it did on high beam? My question is is it possible to fit the bulb upside down or are bike headlights pretty idiot proof?

HI, this is the obligatory hello post. Just got a YBR having passed my CBT and so expect lots of "how does...?" and "Have I done this right?"
