Strapping yourself up with lights is a great way to stay seen on busy roads, particularly when the lighting is sub par, but sometimes light mounts just don't provide the stability you need. Silicone straps can grip, but unless you find the perfect spot, they can slip around on your ride, or even stretch out over time. And then there are the issues of running aero posts, or panniers getting in the way of things. The Light and Motion Vibe Pro Seat Rail Mount manages to solve all of these issues, taking stretchy silicone out of the mix, and setting you up with a securely mounting fixture that stays put on your saddle rails, and is compatible with both oval carbon rails, and round alloy rails. It is secured into place with two clips, using a hex key, and its angle can be adjusted to find the optimal placement for you, so you can stay seen on the ride.
