What people
are saying
Gravity Plus"Great Reliable Light I have been using it for a whole season now, commuting every day with it as well as longer rides. The Braking aspect works great, much better than another light at the same price point. The light is plenty bright and gives me one more way to get drivers attention while in traffic and stopping." -SWB
Asteroid Taillight"This little dude outlasted the expensive Bontrager light I purchased with the Asteroid. It’s going on 3 years, just might need a new strap is all and will buy another." -Mindy
