Nite Rider Lumina 1250 Boost / Vmax+ 180 Combo Lights Light and Bright Bright lights don't always have to be bulky and heavy. They can also be lightweight and compact. The Nite Rider Lumina 1250 Boost Front Bike Light produces up to 1250 lumens to illuminate the road or trail ahead. At only 172g, it is exceptionally lightweight and is suitable as a helmet-mountable option as well as bar compatible. It features 7 light modes and has run times from 1 hour up to 21 hours. The handlebar clamp fits standard and oversized 35mm handlebars. The light also features a low battery indicator so you know when your light only has 20% battery left. The Nite Rider Vmax+ 180 is Nite Rider's first taillight featuring COB (Chip-on-Board) LEDs, which, for cyclists, means it emits highly visible flash patterns 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. For added convenience, the Vmax+ 180 features mode memory, which will power on in the last mode used.
