A clever gem: the Supernova E3 Tail Light 2 for seatpost mounting

For years, it was practically impossible to build a rear light of this size and brightness that was also street legal. The dazzling bright light emitted by these tiny jewels ensures optimum safety, thanks in no small part to clever Twin-Beam technology. The E3 Tail Light 2 is a Supernova product in its purest form. It sits on the cutting-edge of technical possibility while boasting a functional, purist design.

The parking light from the equally-pure rear light are cleverly integrated into the front light's electronics. Such innovation allows for an extremely small, compact design. Weighing in at only 12g, the CNC-milled tail light is 100% waterproof and one of the brightest lights with StVZO approval. The side illumination of the lighting system provides enhanced safety in road traffic.

Unglaublich, wie hell dieses kleine und ultraleichte Rücklicht leuchtet! Ich hab es an den Ausgang des Motors angeschlossen und die Supernova Sattelstützenklemme verwendet. Bin restlos begeistert. Klare Kaufempfehlung.
Edit: Ich habe zunächst die falsche Version bestellt (6V statt12V). Ein Anruf bei BC genügte und es wurde ohne weiteres umgetauscht. Bei diesem Service kauft man doch gerne bei BC.
