Visibility Adapted to Traffic Conditions
The steady or flashing modes mentioned in the specifications allow you to adapt the light signal to the environment. A continuous mode provides a stable presence, while flashing attracts more attention in shared areas or when visibility is reduced.
Position the light so that it remains visible without covering the bicycle's reflectors. A front light should be aimed along the path without dazzling other road users; a rear light should remain unobstructed behind the cyclist, even when the bicycle is carrying a pannier or loose clothing.
Installation, Charging, and Battery Life
Carefully attach the mount to a compatible area, then check that the light does not rotate due to vibration. Before a nighttime ride, check the battery level, verify that the controls work, and select the desired mode. Battery life naturally varies depending on the selected intensity and the automatic functions enabled.
For charging, use the cable and power supply suitable for the manufacturer's specifications. Properly close the connector cover before setting off again. Regular charging helps keep the light available for unexpected trips.
Use in Bad Weather and Maintenance
The stated water resistance applies to splashes or rain according to the rating specified in the characteristics; it does not mean that the product can be submerged. After a wet ride, wipe the housing and wait until the charging port is completely dry before connecting the cable.
Clean the light surface with a soft cloth to prevent dust from reducing visibility. Periodically check the mount and alignment. The light complements reflective elements and the cyclist's vigilance but does not replace compliance with traffic rules.
