You'll love this subtle and stylish tail light that packs a punch with Supernova's twin-bean technology making sure you can be seen at any angle from behind.

250° VISIBILITY If you own a high-performance front light you’ll want to pair it with an equally superior tail light. This is why Supernova have developed the E3 Tail Light 2. Its Twin Beam technology offers an extremely bright power beam towards the back as well as a strong side beam with an angle of 250°.

TWIN-BEAM TECHNOLOGY What’s so special about Twin Beam technology? It combines the light of three LEDs in a smart and very efficient way by using two different beam angles so that you can be seen at any angle from behind.

STAND LIGHT ELECTRONICS The stand light electronics of the rear light have been neatly integrated into the front light. This innovation makes its extremely small design possible. The CNC-machined rear light only weighs 12 grams and is 100% waterproof. It is also one of the brightest rear lights that is road legal in Germany. The new side illumination of the lighting system further increases traffic safety.

SEAT POST MOUNTING The seat post mount can be used to install the rear light on many seat post sizes. The 18 g rear light is the smallest of its kind worldwide, but extremely rugged and waterproof. Ideal for e-Mountainbikes which allows for the integration of the light into the ebike system without the need for a pannier rack. 

MADE WITH LOVE IN FREIBURG, GERMANY Supernova supply the whole world with star light from the south of the Federal Republic of Germany. Their lights are the perfect fusion of quality and design that has no equal. They offer amazing brightness and durability in all conditions. German quality and design at its best. These lights brighten the night without blinding other riders or drivers. Whether in city traffic or on a lonely path through the woods, far away from all civilization, we mainly want one thing from a light: safety through visibility and a well-lit road.
