Select Light Modes
Your bike light has different modes for various needs. Choosing the right mode helps you ride safely.
Learn how to select the light mode on your bike light to improve visibility and battery life.
Steady Beam
The steady beam mode keeps your light on without blinking. It gives a constant light for clear visibility.
This mode is good for riding in dark areas where you need consistent light to see the road and be seen.
Flashing Mode
Flashing mode makes your light blink at regular intervals. This mode helps attract attention from drivers and others.
Use flashing mode in busy streets or when you want to save battery while staying visible.

Many bike lights let you change brightness levels. You can select a low or high light setting.
Lower brightness saves battery and is good for short rides. Higher brightness helps you see farther on dark roads.
