CYCPLUS L7 Radar Tail Light

The CYCPLUS L7 Radar Tail Light is a rear bicycle light with integrated radar for monitoring traffic approaching from behind. Its FMCW radar detects vehicles at distances of up to 160 m and at relative speeds of 6 to 160 km/h. Power is supplied by a 2,000 mAh, 3.7 V rechargeable battery. An IPX6-rated housing withstands powerful water jets, allowing use in changeable riding conditions. These features make it suitable for road cycling, commuting, training, and group rides where awareness of traffic behind you matters.

The light weighs 67 g and measures 76.5 × 37 × 25 mm, giving it a compact rear-mounted form. Rear visibility extends through 270°, so the lamp can be seen beyond a straight rearward line. An accelerometer supports intelligent brake sensing, increasing the rear-light response when the rider slows. Compatible bike computers and other devices can display rider alerts alongside approaching-vehicle distance and relative-speed information. A dedicated on/off switch provides direct control at the light.
