With Cat Eye's Compact Opticube Headlight, this is no reason to ride in the dark. This small-but-powerful light has low, high and flashing modes and puts out an impressive 720-candlepower beam that keeps you visible. It's perfect for regular commuters and the occasional night ride. Keep it in your pack, just in case, the lockable switch eliminates accidental turn ons. And the genius mount attaches to your bars, your stem, or even your helmet with no tools, while a simple clip lets you remove the light easily.
