I have a really bright LED light that works really good. It was very cheaply constructed though. First my bracket broke just from being on to tight (which wasn't tight at all) after one ride. So, I used me dremel to widen the bracket and used epoxy to stick it to the top of my handle bar neck. I actually liked this better. It was completely centered and looks like it was made like that. Clipped my light on and was proud of my forced modification. The next ride I took included going over a couple railroads one way. Second railroad, the light brakes off of the clip it's screwed to. I was not happy, but it's still fixable. I can just epoxy the broke clip back on and it will be nice and solid. Shouldn't have any more problems like that. I can't put batteries in it any more though since the inside cartridge style battery harness broke. How can I wire my light to my 36v battery pack? The light took 4 AA batteries.
The output of this light is great I and don't want to have to get different light. I would have a useless clip on my neck too.
