Review on 🚦 Light & Motion Vis 180 Pro Taillight: Boost Your Safety with 150 Lumens for Daytime and Night Rides. Versatile Mounting, Interchangeability, and Rechargeable Feature. by Jacob Schmidt

This rear light has four modes. The first three modes are very bright, with slightly different intensities and flashes, and the fourth mode is a super-dim (useless) orange glow. This tail light is a fantastic safety device when driving alone, best I have seen. But on a group ride, all three bright modes are too dazzling for drivers behind you (and the super-dark fourth mode is silly - too dark to be of any use). You'd think it would make sense for a company like Light & Motion to enable a glare-free, no-flash red light flashing mode for group rides.
