Vmax+ 180 ALTO features Brake Sensing Technology, indicating to those following behind that you're slowing or coming to a stop.

The Vmax+ 180 ALTO also features COB (Chip-on-Board) LEDs, which for cyclists means it emits highly visible flash patterns in a smaller, more compact package. Its feather-like light weight makes it perfect as a wearable safety light—easily clipping onto straps, belt loops, and more! For added convenience, the Vmax+ 180 features mode memory, will power ON in the last mode used.
