The light on the Super Bright Headlight from Rambo Bikes is very bright and works great on the bike. It illuminates plenty of area when riding in the dark. The rechargeable battery did not work when I tried it, but it comes with a regular battery pack that takes three AAA batteries. My main issue with this product is the mount. The handlebars are tapered so there is not a good place near the center of the handlebars to tighten the mount down to. It loosens up constantly and slides down the handlebars. I ended up securing it with two zip ties on my Savage because it wouldn't stay in place. Not a huge deal, but I don't think the mount was tested much before it was put on the market.
