Bicycle Tail Light Warning Light for Safety

A small light for your rear setup

A compact black bicycle tail light with a round red face and a strap mount. The cylindrical body keeps the light close to your seatpost while the adjustable strap offers a simple fitting arrangement.

Compact dimensions

The supplier lists a 27mm × 36mm light body, confirmed by the illustrated dimension diagram. The same diagram marks the mounting strap at 113mm overall length; this is not a compatible seatpost-circumference specification. Check strap reach and clearance on your bicycle.

Power and output

Supplier specifications list a 200mAh battery and brightness figures of 5Lm or 2Lm. The source calls it a “10W Tail Light”, without providing an electrical test or defining that designation. No runtime is specified; check the light’s charge and operation before each ride.

Body and mounting

The supplier describes ABS and aluminium-alloy construction and a weight of 0.1kg. Product photographs show a USB charging connection accessed by unscrewing the light from its mount. Refit it securely after charging and follow the supplied instructions.

Choose your option

The exact options are Black and New Black. Keep your chosen option selected when ordering; the available description does not define a technical difference between these labels. The photographs show the compact black body and red rear-light face.

Before you ride

Position the light where it can be seen from behind without obstruction from bags or clothing. Check the strap and light before setting off. Add lighting suitable for the route and conditions; a rear warning light does not guarantee that other road users will see you.
