Supernova are renown for their commitment to innovation, design and functionality. The new E3 Tail Light 2 expands technical limits while embracing Supernova's puristic design ideals.

The electronics for the rear light are neatly integrated into the front light thus allowing for the extremely small design of the light. The CNC machined rear light is very elegant and weights in at only 12 grams. It is also 100% waterproof which is a real bonus. Designed in Germany it is one of the brightest rear lights that is complaint with the exacting German road traffic act.

The Tail Light 2 has an ultra bright beam with 250 radius has the affect of greatly enhancing your safety. The Twin Beam Technology creates extremely bright illumination both to the rear and the sides. The indicator beam allows the rider to control whether the light is on or off while sitting in the saddle. Two different beam angles are used by the three LEDs to optimally combine the light output to brightly illuminate the whole of the danger zone behind you.

The twin core wiring is protected by shrink wrap for its whole length and ensures a safe, loss free power transfer along side top performance.

The 6061 aluminium housing is anodized to make it corrosion resistant.

Works with a B&M IQ-XS

ProsSmall but incredibly bright. Great for a dynamo option below a Varia radar
Having read this rear light only worked with Supernova front lights, I was surprised as it was only after I installed with a B&M IQ-XS light that I read them. Just thought I'd share I've had no issues and it works perfectly well. Have used the standard connectors ( not the Supernova plugs ) - so some minor install needed, but all seems good

This light is so small. I fitted it easily to my chainstay so it's no obscured if I use my saddle bag.
Incredibly bright from the rear & highly visible from the sides too.

Great brightness. Small in size and weighs nothing.
Use with the front light and leave on day and night.

can I use this with a Lupine SLx Front Light
10 Dec 2020
can I use this with a Lupine SLx Front Light fitted through a Brose Mag S motor. I already have the specific rear connecting cable for Brose to be soldered to the rear light wire
NO, as this will only work with a Supernova front light.

Supernova Front Light On/Off Switch
21 Oct 2020
When paired with a Supernova front dynamo light, does the front light's on/off switch affect the rear light?
Hello, it's dependent on the front light- from experience, the front light on/ off will turn only the front light off or on. The rear light hs a stand light feature so it will stay on for a period of time regardless.

Using S/A dynohub with B&M front light, want the brightness not worried about standlite, would it work please
Supernova use a DC current so only recommended with a Supernova front light to ensure they do not constantly flicker.

Can this be mounted on a seat stay?
07 May 2020
If not, is there an alternative that can be used with the E3 Pro 2?
the Rixen & Kaul MiniMount for Fitting Light or Reflector (SJS Cycles part number : 37357) can be used to fit this to a seat stay. RT
Can I use this with a Sinewave Beacon?
27 Jun 2019

the dimensions for the beacon are much greater so it is doubtful that these can be used together.
Could I use this with the Edelux II front light?
03 Dec 2017
Could I use this with the Edelux II front light? If so, would the standlight on the E3 tail light function, or would the tail light only be on when moving?

The Supernova uses DC current and would flicker, you would have a better light set up using - SJS Cycles part number :45899W
