[QUOTE="Simon Dinsdale, post: 99953, member: 58"] Bill I have played a bit with LED headlight bulbs and have never found one where the LED is in the right position to focus on the reflector. I have take the mounting plate off the bulb and moved it back and forth until the focal point is correct and the cut off beam is correct which is the problem you appear to have. I then reattached the bulb mounting plate in that position. This is not always possible on some LED bulbs. Ordinary bulbs seem to be fairly compliant with slightly different reflector shapes, where as LED's are not. I fitted the LED bulb to the front of the Rapide for when I took it to Italy in 2015 so I could easily run with it on in the daytime as in Italy I believe any bike over 100cc has to run with headlights on in the daytime. At night the LED just about works but I rarely if never ride at night. LED headlights appear bright to look at, but just don't seem to penetrate very far forward. Simon [/QUOTE]

The Series 'A' Rapide was known as the '********' Nightmare?
