I bought the "Classic British-Style Taillight", it's basically like this one:
I don't think it fits. Bare, the B5's "hump" is in the fender curve itself. The C5, and I assume the G5, have a smooth uniform curved shape, like this military version:
The B5 is the "old Bullet style"; the rear fender is not a smooth uniform curved shape. It's taller, and rather flat on top, then drops down more steeply to the back. Maybe not too easy to see here, but notice how the fender stays follow the curve, and compare it to the one above:
Anyway, I finally got around to removing the stock tail light, and when I hold the new light up to the fender in the place where it should go, so that it's angled right, it rests on the sharper curve so that there is a rather unsightly gap, especially at the top of the light - a gap of almost 1/4 inch. I can reposition it so that it rests on a portion of the fender that better matches the light's curved surface, but it's either way down low with the light pointing towards the ground, or way up high so that it's mostly under my rack, and the license plate is almost horizontal. No pics, unfortunately.
Anybody run into this? Any suggestions? Maybe some sort of chunk of black rubber or closed-cell foam I can cut to fit in there and fill the gap?
