BBB Rear Light BLS-251 Signal Radar

The BBB BLS-251 Signal Radar Rear Light brings advanced rider awareness and visibility into a compact, high-value package. Combining a rear light with integrated radar technology, the Signal Radar detects approaching vehicles up to 190 metres behind the rider and delivers real-time alerts through compatible bike computers or smartphones via ANT+ and Bluetooth connectivity.

One of the standout features of the BLS-251 is its built-in speaker, allowing the radar to operate independently without requiring a cycling computer or phone. This makes it an ideal solution for riders wanting added safety and awareness without a complex setup.

The rear light delivers up to 80 lumens in daylight flash mode and features six lighting modes to suit different riding environments, including Peloton, Flash, Day Flash, and Radar Only mode. With up to 14 hours of runtime and USB-C charging, it is designed for dependable everyday use across road, commuting, and gravel riding.
