2015 Lights Shootout

CatEye Rapid X Lens

A 22 gram total weight is the the highlight of this CatEye Rapid X tail light. And it's not a silly little LED light that's barely visible, but a long LED array that has nice rear and side visibility. For reference, an AA alkaline battery weighs 23 grams, so there's really no reason even for weight weenies to not leave this mounted on their bike.

It's rechargeable of course and it has a variety of flash modes. Time on solid high mode is only one hour but it can last up to 30 hours on one of the flashing modes. It even has a 'vibrating' mode, which is a pulsing mode that is not as distracting to drivers as flash mode.
