Supernova TL3 PRO Rear Bike Light 6-12V DC with Brake Light Function

The Supernova TL3 PRO is a wired rear light built for electric bikes and for bicycles with an integrated electrical system. It runs on a 6-12 V DC supply, so it connects directly to e-bike lighting outputs and to hub dynamo powered setups. The housing measures 20 × 64 × 14 mm and the fitted cable is 2000 mm long.

What sets this rear light apart is its automatic reaction to speed. As you slow down, it switches into a flashing pattern. Under sudden braking, it activates a separate emergency braking flash. Riders behind you therefore read your manoeuvre clearly, without any button press from you.

There is no internal battery inside the unit. Power comes from the bike or e-bike system instead, so recharging and cell swaps never enter the picture. Please note that the mounting bracket is sold separately and is not part of the delivery.

Key Benefits

• Brake light indication – the lamp signals deceleration and makes your riding line easier to predict.
• Automatic flashing while slowing – a clear signal as speed drops, with no extra switches or handlebar controls.
• Emergency braking flash – a dedicated mode that maximises attention during a sudden stop.
• 6-12 V DC power input – matches e-bike lighting circuits and integrated bicycle systems.
• Compact 20 × 64 × 14 mm housing – only 14 mm deep, so it integrates neatly on frames, racks and mudguards.
• 2000 mm cable – long enough to route wiring inside the frame or behind trim parts.
• Battery-free operation – the light is always ready, since it powers up with the rest of your lighting.
• German engineering from Supernova – a brand focused specifically on bicycle and e-bike lighting.

Who Is This Rear Light For?

The TL3 PRO suits electric bikes and pedelecs fitted with a 6-12 V DC lighting output. It also works on bicycles with integrated wiring, for example a lighting system fed by a hub dynamo. If your bike already powers a front lamp from its own circuit, this rear light fits that same architecture.

City riders who commute daily will get the most from it. The same applies to anyone riding after dark or through heavy traffic, because automatic brake indication warns following drivers early. That single function is the core reason to choose this model over a plain steady rear lamp.

Bike mechanics and tuning enthusiasts are a natural audience too. Thanks to the 2000 mm cable, wiring can be run tidily from the rear of the bike forward to a controller inside the frame. Before installation, however, arrange a suitable bracket for your rack, seat post or mudguard.

Technical Specifications

Why Choose the Supernova TL3 PRO?

The main difference from conventional rear lamps lies in the automatic speed response. Most bicycle lights simply glow at a constant output. This model changes its light pattern according to the riding situation, so the signal it sends into traffic carries more information.

The second difference is the power concept. Instead of cells, the light draws from the bike’s 6-12 V DC system. It therefore switches on together with the rest of your lighting, and there is no charge level to monitor before a ride.

The third difference is installation freedom. With a body just 14 mm thick and a cable reaching two metres, the wiring can disappear inside the frame. The result is a clean-looking bike with a fully functional signalling light at the rear.

Frequently Asked Questions

Does the Supernova TL3 PRO work on an electric bike?

• Yes, it is designed as an e-bike rear light.
• It runs on 6-12 V DC.
• It matches integrated e-bike electrical systems.

Will it fit a bicycle with a hub dynamo?

• Yes, provided the lighting system supplies 6-12 V DC.
• Bicycles with integrated wiring are a supported application.
• The light then activates with the rest of the circuit.

How does the slowing flash differ from the emergency braking flash?

• The slowing flash starts as your speed drops.
• The emergency braking flash triggers during sudden braking.
• Both modes work automatically.

Is a mounting bracket included?

• No, the bracket is purchased separately.
• Choose one suited to your rack, seat post or mudguard.
• Prepare it before you begin the installation.

Does the light contain a battery?

• No, there is no internal battery.
• Power comes from the bicycle or e-bike system.
• You never need to replace cells.

How long is the cable?

• The integrated cable measures 2000 mm.
• That equals two metres of routing length.
• It allows wiring to be hidden inside the frame.

How much space does the housing need?

• The body measures 20 × 64 × 14 mm.
• Its depth is only 14 mm.
• Compact dimensions ease integration on the bike.

For riders who want their rear lighting to communicate more than presence, the Supernova TL3 PRO adds automatic brake signalling to a compact, wired package. Pair it with a bracket that matches your frame or rack, route the 2000 mm cable along your preferred path, and connect it to your 6-12 V DC output.
