Headlamps with Red Light: Choose a Useful Night Mode

It is commonly used for close-range tasks when you want less bright white light in a dark setting, such as reading a map or moving around camp.

Depending on the model, it may provide continuous low-level illumination or a flashing signal. Check the manual for its mode and purpose.

Manufacturers often describe red modes as helping preserve night vision, but the effect depends on brightness and how you use the light.

Do not assume it meets bicycle-lighting rules. Use legally required bicycle lights and treat headlamp modes as supplemental.
