CATEYE RAPID micro AUTO (TL-AU620) | Lightweight, Compact Rear Light with Automatic Illumination

Small, lightweight, yet reliably safe. A USB rechargeable rear light that automatically illuminates by detecting darkness and vibration.

The CATEYE RAPID micro AUTO (TL-AU620) is a compact USB rechargeable rear light equipped with a brightness sensor and a vibration sensor.

It automatically illuminates when it detects darkness and vibration in places such as at night or in tunnels, and maintains illumination for about 50 seconds after stopping due to its afterglow function. It is an auto-light model that is easy to use for daily commuting and city riding.

Despite its lightweight and compact body of about 21g, it features three highly visible modes: constant, alternate, and rapid. The alternate mode, where two LEDs flash alternately, enhances visibility from the rear while also being energy-efficient.

You can switch between auto mode and manual mode. This allows for flexible use day or night, as you can manually force illumination when needed.

Furthermore, it is equipped with a battery indicator and a battery auto-save function. When the battery level is low, it automatically switches to flashing mode and can still be used for about another hour.

It comes with a bracket that can be easily attached to the seat post without tools. This compact yet reassuring rear light is perfect for everyday use.

Although it is quite compact and lightweight, when actually used, it ensures good visibility from the rear.

The auto-illumination function is particularly convenient. It automatically lights up when entering tunnels or dark roads, making it very comfortable for commuting and city riding. The afterglow function, which maintains illumination for a while after stopping, also provides a sense of security.

Its small size makes it less likely to detract from the overall aesthetic of the bike, making it a suitable rear light for those who want to "ensure safety without being too conspicuous."
