Supernova E3 Tail Light 2 – Rack Mount, 6V, Black
The Supernova E3 Tail Light 2 – luggage rack version (6 V, N-TK2-BLK) – is a small, 100% waterproof dynamo tail light. It runs from the 6 V system of your Supernova dynamo front light and shares its parking-light function, so you stay visible even at red lights.
Why the E3 Tail Light 2?
Dynamo powered. Always on when you ride, never runs flat. 
Parking light. Stays lit while you wait at junctions, together with your Supernova dynamo front light. 
100% waterproof. Supernova specifies it as fully waterproof – for year-round riding. 
Small and simple. Connects to the tail-light output of the front light with a single cable. 
Guarantee. 5 years; at least 10 years repairability.
Protected on the rack
The rack version fits racks with the standard 50 mm hole spacing. It sits at a good height and is protected by the rack itself.
The 1,800 mm cable runs to the tail-light output of your Supernova dynamo front light.
Important: 6 V only. A higher voltage damages the electronics – this light is not suitable for current Bosch e-bike systems.
Who is it for?
- Hub-dynamo bikes with a Supernova E3 front light. A matching rear light from the same system.
- Bikes with a luggage rack. Touring, trekking and city bikes.
- Year-round riders. A light that is always on.

Send us a photo and we will tell you what you need. Supernova was founded in Germany in 1997. It started with a headlight its founder built for his own night training rides – after around 20,000 kilometres of riding in the dark, the company was born. Supernova lights are developed in Germany, and its top models are produced in Gundelfingen near Freiburg. The brand builds machined aluminium housings and lenses that put the light where you need it, and backs its lighting systems with a 5-year guarantee and at least 10 years of repairability.About Supernova
