NiteRider's Mako 100 features a bright 100 lumen Cree LED that has 3 modes: high, low, and flashing (for increased daytime visibility). Its "gills" emit a red light so it can be seen from the side too. This sweet light attaches to your handlebars without tools.
Run time: 30/90/180 hours (high/low/flash)
2 AA batteries included
