Keep track of what's ahead on dusk or dawn roads and help ensure that motorists are aware of your presence with NiteRider's Lumina 550Solas 30 Combo Light Kit. Designed to help you see and be seen, the unfussy headlight and tail light mount cleanly to bars and seatposts to keep you safe during the times when you can't or don't want to avoid riding in the dark. To help you see the contours of the road or trail ahead, the handlebar mounted Lumina 550 offers you the choice of four steady modes and up to 550 lumens of brightness. NiteRider also adds a battery conserving daylight flash mode option for use on gloomy, rainy days or shady trails. It's built with NiteRider's Intellicharge feature as well, which enables it to get up to a full charge in just three hours if connected to a high power source of 500mA or more. The Solas 30 tail light provides you with two steady and two flash modes, helping you stay visible to fellow riders and motorists in traffic. It also features NiteRider's Group Ride mode so that you can leave it on for safety in critical mass without distracting everyone behind you.
