Safely ride into the night with the Glo front safety light and Ember taillight. The Glo throws a 12-lumen beam to mark your path on darkened city streets, while the Ember emits a bright red 8-lumen strobe or beam to alert others of your presence ahead of them. Both lights are USB rechargeable, and use simple silicone straps to quickly attach to just about any part of your bike or helmet.
