Not only does the NiteRider Sentinel 40 tail light deliver an impressively bright 40 lumens of LED illumination, but this light features the ingenious Laser Lanes feature. The Sentinel 40 projects laser lines onto the ground on either side of the bicycle which creates a virtual bike lane and suggests a safe passing distance for motorists. The Sentinel 40 features both steady and flash modes and a run time of 4.5 to 36 hours (depending on mode). Re-charging the light is convenient via the USB cable -- a four-hour process for a full charge. There's also plenty of versatility in placement of the tail light with a quick release bracket for seat post mounting plus a universal clip for attachment to clothing or a bag.
