Brompton Rear Dynamo Lamp - Brompton

No, the Brompton Rear Dynamo Lamp is powered by the bike's dynamo hub, so no batteries are required.

This lamp is specifically designed for Brompton folding bikes equipped with a dynamo hub and a compatible front light.

The 'Safe Stop' feature keeps the light illuminated for up to four minutes after you come to a complete stop.

The part code is QVDYNRLAM-SOLO, and the part number is 9020454.

While it can be connected, its full functionality and intended operation often rely on the electrical system set up for a front dynamo light. It's recommended to have both.

Use a soft, damp cloth to clean the lens. Avoid using any abrasive cleaning agents.

Yes, the lamp is compatible with Brompton bikes that are equipped with or without a rear rack.

Verify that the dynamo hub is functioning correctly. Check all electrical connections between the dynamo, front light, and rear lamp for looseness or corrosion. Ensure the wheel is spinning sufficiently to generate power.

Inspect wiring connections for intermittent contact. A loose connection is the most likely cause. Ensure the dynamo is properly seated and the wheel spins freely without obstruction.

Confirm that the 'safe stop' function is enabled (if there's a switch) and that the light is receiving adequate power from the dynamo. Some dynamo systems may require a minimum speed to maintain the capacitor charge for the 'safe stop' feature.

Inspect the lamp for any visible physical damage. Tighten the mounting hardware securing the lamp to the bike. If the lamp is broken, it may need replacement.
