• Intended use: front bicycle headlight for visibility and road illumination

How to use

Mount the headlight on the bicycle according to the frame’s dynamo mounting points, ensuring the wired connection to the dynamo is secure and insulated from moisture. Adjust the angle of the lamp so the beam illuminates the road ahead without dazzling oncoming traffic. The headlight operates automatically while the dynamo turns; stop pedaling or when the dynamo is inactive, the light will not be powered. Periodically check the wiring and mounting bracket for corrosion or looseness and clean the lens to maintain optimal light output.

Recommendations

For reliable performance, use the headlight on bikes with functional dynamos that are correctly aligned. Inspect electrical connections regularly and avoid kinking or crushing the supply cable. Keep the headlight lens clean and free of obstruction to preserve the designed light pattern and visibility.
