Cateye Flex Tight Headlight Bracket

Good product from a reputable brand

I've run Cateye lights for years. The company tends to use the same mount for several generations of products. When you have multiple bikes, it's handy to swap one headlight among them, and if you need to replace a light, one that fits your old brackets is a big plus. The bracket is less fiddly than the strap-type mounts.
