This combo features NiteRider's Lumina OLED 1200 Boost headlight, which features five light settings and four flashing modes for varied conditions. Up to 1200 lumens are delivered via a Collimator lens, which distributes the light evenly while projecting a generously wide beam. A digital display makes planning adventures easy thanks to its precise battery run times. It recharges from a standard USB outlet, and has an Intellicharge feature that minimizes the recharge wait. The Solas 250 tail light has an easy on and off mount that straps to your seatpost, letting you easily switch it from bike to bike when necessary. It features two solid and two flashing modes, as well as a Group Ride mode that lets you stay safe by increasing your visibility without distracting the riders around you.
