The Allty 1200U Front Light + SeeMee 50 V2 Rear Light is a front and rear light set built around an anti-glare lens and a lightweight out-front mount that holds the front light ahead of the bars. A lock function keeps either light from switching on by accident, and a memory function brings each one back in the last mode selected. The SeeMee 50 V2 rear light adds up to 50 lumens through an Optillumin lens. What Our Gearhead(R) Experts Are Saying:"On long climbs, one touch on the handlebar remote changed the setting on both lights, so my hands stayed on the bars. FTR LightSync Control kept the front light and the SeeMee 50 V2 in step."
