While I've got the headlight and its shell off my 1100 to change a broken indicator stem, I remembered a duff tacho bulb which I've dug out of its hiding place.
Trouble is I can't find out a rating so I can buy another one.
Anyone know what I need to be asking for?

). I've just put it under a microscope at work - there's a very faint (16 year old) legend on the bulb which my crap eyes couldn't see at home.
