Review on 🚴 CHIYOU Vibration Sensor Waterproof Shockproof Lamp: Neon Tire Valve Led Light - Set of 2 for Bicycle Wheels by Jason Vigil

These work great on my road bike when riding at night. It is very visible (from 360 degrees, not just from the side). Very reliable. The 3 button batteries included will last around 12-15 hours before starting to dim. Batteries are easy to replace. They are very waterproof. They are very sensitive to movement, which turns them on. So if they're spinning on your wheels, they're always on. I love them and would recommend them to anyone who wants to draw attention to them when driving in the dark.
