CATEYE RAPID X2 KINETIC (TL-LD710K) | Rear light with Kinetic function to indicate deceleration

Clearly signals "deceleration" to the rear. A highly visible rear light with surface emission and Kinetic function.

The CATEYE RAPID X2 KINETIC (TL-LD710K) is a USB rechargeable rear light equipped with a "Kinetic mode" that incorporates an acceleration sensor.

When deceleration is detected, it automatically switches to high mode (approx. 50 lumens) to alert following vehicles of deceleration. This high-performance model enhances safety for city riding, road cycling, and group rides.

It adopts a wide light-emitting design using surface-emitting LEDs, improving visibility not only from the rear but also from diagonal directions. It is a compact yet highly noticeable rear light.

The bracketless attachment with a rubber band allows it to fit snugly against the seat post. It pairs well with the sleek silhouette of road bikes, giving a clean look.

It features three modes: Low, Flashing, and Rapid. Furthermore, it supports daytime running light use, providing high visibility day and night.

It also features a battery indicator and a battery auto-save function. When the battery level is low, it automatically switches to flashing mode, allowing continued safe use.

This CATEYE rear light is practical, lightweight, compact, easy to use, and emphasizes enhanced safety.

The Kinetic function, which automatically emits a strong light during deceleration, is quite practical and provides peace of mind in cities and on roads with heavy traffic.

As it's a surface-emitting type, visibility is high, and it's quite easy to spot from behind. It pairs particularly well with road bikes, and its design that adheres to the seat post also gives a clean appearance.

For those who want to balance "small and smart aesthetics" with "safety," I think this is a very user-friendly rear light.
