Cygolite lights the way with the Metro 550. This bright, USB-rechargeable light throws 550 lumens in a wide beam with side illumination ports that are great for commuters and trail riders alike. It features a unique SteadyPulse mode that alerts night time motorists with pulses of light while still constantly lighting your path and a DayLightning mode that creates super-visible flashes for enhanced visibility during the day. It also packs high, medium, low, and walking modes to customize your output and run times. Plus, a tool-free handlebar mount makes installation simple.
