Small, light, yet highly noticeable. A rechargeable rear light that's easy to use for city riding and group rides.

The CATEYE RAPID mini (TL-LD635) is a USB rechargeable rear light that packs high visibility into a lightweight and compact body.

Weighing approximately 21.5g and featuring a small size, it maintains the bike's overall aesthetic and blends naturally with road bikes and cross bikes. It's a versatile model suitable for everything from daily commutes to weekend rides.

Combining three high-intensity LEDs with OptiCube lens technology, it ensures excellent visibility despite its compact size. With a brightness of up to approximately 25 lumens, it enhances your presence from behind.

It features four modes: constant, flashing, rapid, and group ride. The group ride mode, in particular, is designed for ease of use in groups, ensuring visibility while minimizing glare for trailing riders.

Additionally, it's equipped with a battery indicator and a battery auto-save function. When the battery level gets low, it automatically switches to flashing mode, allowing you to continue using it safely.

It comes with a bracket that can be installed without tools, and with optional brackets sold separately, it can also be attached to saddle rails or bags. This rear light is recommended for those who prioritize lightness and ease of use.
