Halo Beta 50 is a safety-enhancing 50 lumen rear light with an intelligent brake light sensor. When a cyclist slows down, the light automatically turns on at 100% for three seconds, ensuring that those behind you will see you in time.
The light has five modes: two standard flashes (70% and 30%), slow flash (70%), combined slow and fast flash, and a breathing mode with brightness increasing and decreasing from 0-100%. The internal 400 mAh Li-Poly battery charges in just one hour via USB. Durable aluminium body and IP65 waterproofing ensure reliable operation in all weathers.
Three different types of mounting brackets are supplied: for the saddle post, saddle rail and luggage rack - easy to install without tools.
