Thanks for the info. I had heard that the BMW C1 headlamp was the same. There is one for sale on ebay right now, however it does not have the same part number. It is hard to discern the full text from the picture, but it is something like "tri.o.m 2080..."
I have to agree with your assessment: is indeed utter crap! If I can't resolve this problem, I might just remove it completeley and get a daylight MOT! I would hardly notice the difference as I only use the bike during the summer months.
How about running the whole caboodle through a bandsaw to get the lens off the pathetic black plastic silvered bit then moulding a new piece to fit with better adjustment? Just a thought... new LHD ones are over £100 - scary, but then it is from Built Minus Wit.
The BMW C1 headlight is same as the Guzzi 1100 sport. The can be purchased from Motor works Homeforth part number 63122350525 £94.54p inc vat +carriage special order (2010 price) parts list http://realoem.com/bmw/showparts.do?model=0191&mospid=51722&btnr=63_0621&hg=63&fg=05&hl=2
