Rear Light RAVEMEN CL100 100 lm COB USB Auto On/Off and Brake Light

The RAVEMEN CL100 is a compact, lightweight and intelligent bicycle rear light combining a maximum output of 100 lumens, an impressive 300° visibility angle and smart automatic brake detection and on/off functionality. Featuring a horizontally positioned elongated COB-LED light strip, the CL100 is designed to improve cyclist visibility in various traffic conditions, providing effective illumination both directly behind and to the sides. Thanks to its minimalist design and exceptionally low weight of just 30 g, it is an excellent choice for road, gravel, mountain and urban bicycles.

One of the CL100's standout features is its 300° wide-angle visibility, helping ensure that cyclists can be seen from multiple directions. The horizontally arranged COB-LED light strip creates a broad, uniform illuminated surface that enhances visibility at intersections, in urban traffic and on open roads. With up to 100 lumens of output, the rear light helps riders remain noticeable during daylight, at dusk and after dark, improving safety in a wide range of riding conditions.

The integrated saddle rail mounting system allows the rear light to be positioned neatly underneath the saddle. This streamlined arrangement keeps the light aligned with the bicycle and creates a clean, aerodynamic appearance without requiring bulky accessories on the seatpost. The included ABM25 saddle rail mount is particularly suitable for performance-oriented bicycles where minimalist design and compact equipment are important.

An additional ABM14 seatpost mount is included, allowing the light to be installed on round seatposts and certain aerodynamic seatposts with compatible dimensions. These two mounting options provide greater flexibility and allow riders to select the most suitable installation position for their bicycle.

Additional safety is provided by the intelligent brake detection function. When the bicycle decelerates, the integrated sensor automatically activates a brighter brake warning light for two seconds, alerting approaching road users that the cyclist is slowing down. This is particularly useful during urban commuting, when approaching intersections and in situations where frequent braking requires increased awareness from other road users.

The automatic on/off function makes the rear light convenient to use while helping conserve battery power. When the bicycle remains stationary for two minutes, the CL100 automatically switches off. It switches back on when movement is detected, reducing the need for manual operation during stops. This makes it particularly practical for everyday rides and longer training sessions.

The integrated 700 mAh rechargeable lithium-polymer battery provides up to 160 hours of runtime, depending on the selected lighting mode. Its extended battery life reduces charging frequency and makes the light suitable for longer cycling adventures. Charging is handled through a concealed USB-C port, helping protect the charging connection from moisture and dirt.

The CL100 also features an intelligent three-level battery indicator. When the light is switched off, pressing the power button displays the remaining battery status. Green indicates 20–100% capacity, red indicates 5–20%, and flashing red warns that less than 5% remains. This allows riders to check the battery level quickly before setting off and recharge when necessary.

The IPX6 waterproof rating provides reliable protection against heavy rain and water splashes, allowing the rear light to perform in demanding weather conditions. Its compact dimensions of 67 x 31.7 x 20 mm and ultra-low weight of just 30 g make it an ideal option for cyclists seeking effective lighting without unnecessary bulk or additional weight.

The RAVEMEN CL100 combines excellent side visibility, intelligent safety features, long battery life and versatile mounting options. Its automatic brake warning light, motion sensor and included saddle rail and seatpost mounts make it a dependable choice for both performance cycling and everyday commuting.
