Rear bike lights help make you more visible to people approaching from behind, whether you are commuting through town or heading home along country lanes. Find a rear light to suit your bike and journey, then pair it with a front light or explore light sets if you need both.
Why Choose Rear Bike Lights?
A rear light adds an active point of visibility at the back of your bike. Choosing one with suitable modes, a clear mounting position and enough runtime helps you stay prepared for early starts, evening journeys and changing light conditions.
What to Look for in Rear Bike Lights
- Visibility and modes: Consider the viewing angle as well as the quoted output. Check the available steady and flashing settings so you can choose a mode suited to the conditions, and a lower output for riding closely with others.
- Mounting and clearance: Check the mount fits your seatpost's shape and dimensions, especially with aero designs. Position the light so a saddle bag, luggage or clothing does not obscure it, and check compatibility if you need an alternative mounting point.
- Runtime and charging: Compare runtime in your intended mode and allow extra charge for longer journeys or delays. Consider the battery indicator, charging connection, ease of removal and water resistance for everyday use.
