The NiteRider Swift 500 features everyday reliable performance in an economical ultra compact head light. Sporting features like an easy on and off handlebar strap mount, low battery indicator and to top it off, it's USB rechargeable; making it the perfect light of choice for commuters and cycling enthusiasts.  Although small in size, make no mistake, the Swift 500 packs a big punch with a maximum light output of 500 lumens! Powered by an internal lithium-polymer battery, in walk mode, the Swift 500 can run for up to thirty two hours before it needs a charge. Vmax+ 150 is NiteRider's first taillight featuring COB (Chip-on-Board) LEDs, which for cyclists means it packs more punch in a smaller, more compact package. Its feather-like light weight makes it perfect as a wearable safety light—easily clipping onto straps, belt loops, and more. Features Daylight Visible Flash (DVF) technology as well as Group Ride Mode where you can be seen without distracting fellow cyclists' attention from the pavement or dirt. The USB rechargeable Vmax+ meets all required FL1 Standards for impact testing and dust/water resistance.
