OSRAM LEDsBIKE RACE REAR – an LED rear bike light that responds to braking

OSRAM LEDsBIKE RACE REAR LEDBRL102 is a rechargeable LED rear bicycle light designed to improve rider visibility. It combines a red rear light with an integrated brake sensor, two operating modes and USB-C charging. According to OSRAM, the light provides up to 13 hours of operating time.

Key benefits

• Integrated brake sensor – detects deceleration and activates a more prominent light signal for road users behind the bicycle.
• Two operating modes – Steady and Automatic provide different options for everyday riding.
• Up to 13 hours of use – the integrated lithium-ion battery means no connection to the bicycle's electrical system is required.
• USB-C charging – convenient charging through a widely used connector standard.
• Flexible tool-free mount – designed for straightforward installation on the bicycle.

How does the brake-light function work?

LEDSBIKE RACE REAR uses an integrated sensor to detect braking. When the bicycle decelerates, the rear light provides a more noticeable signal to riders and drivers approaching from behind. The brake-light function remains active in both Steady and Automatic modes.

This product is primarily a rear signalling and visibility light. OSRAM does not publish luminous flux, luminous intensity or beam-range figures for LEDBRL102, so no unsupported output or range claims are used here.

Operating modes

• Steady – standard rear-light operation.
• Automatic – automatic control of the light's operation.

The brake-light function remains active in both modes.

StVZO approval and road use

OSRAM states that LEDsBIKE RACE REAR is StVZO-approved and carries a K-Mark for road use in Germany. StVZO approval should not automatically be interpreted as approval under the national road-lighting requirements of every other country.

For use in Poland, the bicycle and its lighting must comply with applicable national equipment and installation requirements. Polish rules require a red rear position light as well as a separate non-triangular red rear reflector. The available LEDBRL102 documentation does not confirm that this product incorporates the required reflector function.

Construction and protection

The current OSRAM data sheet specifies an IP54 protection rating. The light uses a 3.7 V lithium-ion battery and charges via USB-C. OSRAM provides a 2-year warranty.

Typical applications

• daily bicycle commuting,
• urban and suburban riding,
• training and recreational cycling,
• longer rides where automatic brake signalling is useful.

Technical data

Mounting and package information

The product is supplied as one rear light. The manufacturer's instruction illustrates a flexible seatpost mounting system and a USB-A to USB-C cable. OSRAM does not provide a separate complete textual packing list in the available documentation, so the package should not be described as a complete installation kit without further confirmation.

The light has its own 3.7 V rechargeable battery and therefore does not require a 12/24 V wiring harness, relay or connection to a vehicle electrical system. Fit should be checked before installation on unusual or aerodynamic seatposts.

Frequently asked questions

Does the brake function work in both modes?
Yes. According to OSRAM's instructions, the brake-light function remains active in both Steady and Automatic modes.

Does the light require a 12/24 V electrical connection?
No. LEDBRL102 uses its own 3.7 V lithium-ion battery and charges via USB-C.

Is it road legal?
OSRAM confirms StVZO approval with a K-Mark for Germany. In other countries, road use depends on compliance with the applicable national bicycle-lighting requirements.

Does it replace the required red rear reflector?
No reflector function has been confirmed in the available OSRAM documentation. Where a separate reflector is legally required, it should be treated as a separate bicycle component.
