The CatEye Rapid 1 Taillight is everything you could want in a taillight. Simple and quick to mount, the Rapid 1 utilizes a high-power SMD-LED that emits a unique rapid flashing pattern making you visible quickly even from a distance. It's USB rechargeable thanks to an on-board lithium ion battery and has 4 modes to give you options without making it frustrating to shut off. The low battery warning light will make sure you're never left in the dark and thanks to a slim light weight profile, it's the kind of light you can leave on your bike all the time. You never know when you're going to be caught out after dark, but one thing you can count on is the CatEye Rapid 1 having your back.
