The rear light from Gundelfingen comes with an aluminium housing and protection class IP67. A swivelling bracket allows it to be mounted in various positions on the bike. Supernova offers a special bracket for saddlebags as an option. The Redstream Pro is suitable for road, gravel, commuter and bikepacking use.

Brake light and emergency brake light

A sensor recognises heavy deceleration and automatically activates a brighter warning signal for following road users. The brake light and emergency stop light function complies with the latest StVZO standard. According to the manufacturer, the light output is particularly powerful.

Battery system and runtime

The battery system is designed to maximise the service life of the battery and automatically brings it to the correct charging temperature at low temperatures. The StVZO version runs for up to 20 hours, the international version with flashing mode for up to 100 hours. The intelligent charging electronics control the charging process.

Warranty and availability

Supernova gives a 5-year guarantee on the Redstream Pro including battery. The planned repairability is at least 10 years. The rear light is available now for 129.00 euros.
