The Busch & Müller Toplight Line Plus embodies German excellence in dynamo rear lighting. Thanks to its patented LineTec technology, this LED light transforms your nighttime safety by offering a continuous 90 mm light band instead of a simple red dot. This innovative optical system, visible at 320°, allows motorists to estimate your distance and speed with unmatched precision — a considerable safety gain in urban and road traffic.

LineTec Technology: the optical revolution

Unlike conventional rear lights that emit an isolated light point, the Toplight Line Plus integrates two high-power LEDs diffused by a patented lens system. Result: a homogeneous and bright red ribbon that offers superior spatial perception to following drivers. The light also extends laterally, guaranteeing 320° panoramic visibility, even from blind spots.

Technical highlights

• Automatic standlight: Powered by an integrated capacitor, the light remains on 4 minutes after stopping the bike, without battery or cell. Full charge in only 3 minutes of pedaling. Manual deactivation possible via rear button.
• Integrated Z reflector: Large approved reflective surface, ensuring passive safety even when light is off.
• Ultra-light and compact: Only 53 grams for 16.5 mm thickness, elegant and discreet design, ideal for thin or narrow racks.
• Simplified installation: Connection via 2.8 mm central male terminals or patented system without cable stripping (insert cable, activate lever — done).
• Multiple approvals: StVZO compliant (Germany) + France marking. Entirely manufactured in Meinerzhagen (Germany).

Available variants

The Toplight Line Plus is offered in two mounting center distance versions to fit all racks:

• 50mm version (323ALT-02): EAN 4006021006225 — standard center distance, compatible with most Tubus, Racktime and Brompton racks.
• 80mm version (323/8ALT-02): Widened center distance for wider racks or specific configurations.

Both variants share the same technical characteristics (weight, LineTec optics, standlight) and differ only in mounting spacing.

For whom and why?

This rear light is designed for urban cyclists, bike commuters and cycle tourists equipped with a dynamo hub and demanding reliability, performance and aesthetics. Its extreme lightness, exceptional visibility and sleek design make it a reference choice for any bike equipped with a rack. Compatible with all Busch & Müller dynamo front lights and most systems on the market.
