NiteRider's Mako 150 features a bright 150 lumen Cree LED that has 3 modes: high, low, and flashing (for increased daytime visibility). Plus, its "gills" emit a red light so it can be seen from the side. This sweet light attaches to your handlebars without tools.
Run time: 20/60/120 hours (high/low/flash)
2 AA batteries included
