Supernova E3 rear light

Supernova's E3 tail light 2 is designed to be used with their front-facing dynamo lights and it's a brilliant bit of kit in every sense. It's tiny, powerful, well-designed and beautifully made.

Weighing in at just 15g the tail light 2 is effectively just three LEDs and an alloy mount. There's no standlight in there, but if you pair it up with a Supernova E3 front light the tail light will run off that when you stop. Supernova say it'll stay on for four minutes, in reality it's double that.

There are two versions of this light, the one we have (that attaches via two bolts to a rack plate) and a seatpost-mountable one with a rubber O-ring. Since the seatpost one is deisgned to be mounted vertically they're slightly different in design but both have a good range of visibility and are very bright. The horizontal unit has two outer LEDs with a sort of reverse-conical lens that disperses the light, and there are machined grooves in either side so that you can see it well from the side. On top of that, the LED lenses extend out of the alloy body for even better visibility. The middle LED is a standard domed shape and brighter than the other two, and there's a handy groove cut into the top so it's easy to check the light is on when you look over your shoulder.

In use with an E3 Pro 2 front light and an SP hub dynamo, and it's a fit-and-forget joy. I mounted it to a Tortec Velocity rack (I had to drill and tap some holes in it as it doesn't have a standard rack plate) and that's been the sum total of effort. No batteries, no worrying about whether it's on, no worrying about being seen. It's as bright as a battery-powered LED unit, tiny, neat and good-looking. All-round visibility is excellent.

Any problems with it? Not really. It's expensive, and ideally you'll already have an E3 front light which isn't cheap either. But you're getting a quality item here, no doubt about it. Think of it as an investment.

There's been some talk on light reviews in the past as to whether a small light is inherently less safe because drivers find it harder to work out how far away you are. My take on that would be that if you're pinning your hopes of safety on the ability of a driver to succesfully triangulate distance from 100m away based on something that's at best 10cm across, your prospects aren't good.

I'd rather rely on a nice bright light that'll get you seen. This is that. On an overnight ride or on really busy roads I'd be tempted to supplement it with a flasher, but it's plenty good enough for daily duties and should last pretty much for ever.

Verdict

Excellent little rear light that's the perfect companion to Supernova's E3 front beams

road.cc test report

Make and model: Supernova E3 Tail Light 2 dynamo rear light

Size tested: grey

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

For many years it was not possible to build a rear light with such small dimensions and such brightness that is road legal in Germany. The dazzling bright light of these precious gems guided by the clever Twin Beam Technology provides the best possible safety. The new E3 Tail Light 2 is a typical Supernova product that is expanding the technical limits while having a functional, puristic design.

The stand light electronics of the puristic rear light has been neatly integrated into the front light. This innovation makes the extremely small design possible.The CNC-machined rear light only weighs 12 g 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.

Such a shame this light is only compatible with its makers lights.

Can you please please please review some other rear dynamo driven lights?The B&M seculla seems to be about the next best option for dynamo users and has no compatitibilty issues and so is worthy of a comparative review.

It is a weird choice by Supernova to only make their lights compatible with each other.

Try the B&M toplight or Philips SafeRide ranges bobinski. As bright as the Supernova*, but bigger lights and with built-in reflectors.

*I'm comparing with the first iteration of the taillight I had. This one might be brighter...

I've been running Supernova lights for quite a few years now (E3 Triple non-StVo version) with a Supernova Dyno hub and an Airstream headlamp for night racing and bikepacking and I have to say, I LOVE their products and the service, on the rare occasion it's needed, is fantastic!
