Rear bike light Rockbros LKWD-R1 with laser and remote control, rear LED safety light with lane laser

Rockbros LKWD-R1 is a rear bike light that combines a bright LED lamp, integrated lane laser markers and a wireless remote control. Designed for mounting on seat posts, this compact unit improves rear visibility and projects clear side lanes to alert motorists and other road users during low-light conditions. The housing is water-resistant and charges via USB, offering multiple light modes for commuting, city cycling and evening rides.

Advantages

The light integrates a high-visibility LED at its core with two laser lane markers that project parallel guides on the road surface, enhancing lateral space awareness. A simple wireless remote lets the rider switch modes without taking hands off the handlebars. The compact, durable housing is designed for seat post mounting and resists splashes, while USB rechargeable power eliminates the need for disposable batteries. Multiple flash and steady modes provide flexible visibility options suited to different traffic and weather conditions.

How to use

Mount the Rockbros LKWD-R1 on the seat post using the supplied strap or bracket, positioning the unit so the LED faces directly rearward and the laser markers have an unobstructed projection path to the ground.

Regularly check that the light and lasers are clean and properly aligned for consistent visibility.

Usage recommendations

For optimal safety, use a steady LED mode in low-visibility conditions and enable the lane lasers when cycling near traffic to increase lateral awareness. Ensure the device is securely fastened and the remote is positioned for easy access without compromising control of the bicycle. Recharge the unit after extended use and avoid prolonged exposure to heavy rain despite water-resistant design.
