Visibility: The primary purpose of a bike tail light is to make you visible to motorists and other road users. Look for a tail light with high visibility, featuring bright LEDs that can be seen from a considerable distance.
Brightness: Choose a tail light with adjustable brightness settings. This allows you to customize the intensity of the light depending on the conditions. Use a brighter setting for darker environments and a lower setting when there’s more ambient light.
Water Resistance: Ensure that the tail light is at least water-resistant or, ideally, waterproof. This is essential for riding in rainy conditions or if you encounter unexpected weather changes.
Mounting Options: Look for a tail light that is easy to mount securely on your bike. Quick-release mounts can be convenient for removing the light when you lock up your bike to prevent theft.
Angle Adjustment : Some tail lights allow you to adjust the angle to ensure the light is directed towards traffic. This can be particularly useful if you have an unconventional bike setup.
Durability: Choose a tail light that is built to withstand the rigors of cycling, including vibrations and occasional falls. Look for lights with robust construction and materials.
