Compact aluminium tail light for cyclists

The ROCKBROS mini tail light attaches to the handlebar and weighs very little. It suits commuters and leisure riders who want a bright rear signal without a bulky housing. The silver aluminium body keeps the profile slim on any bike.

IPX6 waterproof and 30-second auto-off

The IPX6 rating protects the internals from heavy rain and road spray. Motion and light sensors switch the light off after 30 seconds of inactivity or when daylight is sufficient. Type-C USB charging replenishes the lithium-ion cell without a proprietary cable.

Brake sensing brightens automatically under load

When the rider brakes, the light intensifies to warn following traffic. Five selectable patterns include steady, breathing, normal flash, fast flash and jumping flash. Manual modes disable the sensors for continuous output on long night rides.

Questions about this item

How do I mount this ROCKBROS tail light on my handlebars and what is the common mistake?

Slide the included handlebar mount onto the bars and tighten the clamp; the step riders miss is orienting the lens straight back so the brake sensor faces rearward for proper detection.

What maintenance will the internal lithium-ion battery need over time?

Recharge via the Type‑C USB port when runtime drops; the sealed cell is not user‑replaceable, so keep the port clean and avoid deep discharge during storage.

At what point does the auto‑off sensor cut power during a ride stop?

The motion sensor powers the light down after 30 seconds of complete stillness, so it will shut off at traffic lights unless you switch to a manual mode.
