Smart Bike Tail Light with Bluetooth, Customizable & Waterproof

Highly Customizable Intelligent Light

The L308 intelligent expression tail light features 96 COB LEDs that you can customize freely. Connect it to the OnelapFit APP to draw and create your own unique light styles on the screen. Customize up to 3 unique emojis—patterns, scrolling messages, and GIFs.

15 Emoji Storage

Equipped with six preset emojis, the L308 intelligent expression tail light offers up to 15 emoji storage, doubling the storage capacity of most other tail lights. Use the single-button design for easy emoji switching with just one press. Additional emojis can be created in the OnelapFit APP.

Smart Braking Sensor

The L308 intelligent expression tail light comes with a high-precision acceleration sensor. This sensor can quickly detect even slight braking and enter a 3-second high-intensity flashing mode to alert vehicles and pedestrians behind you. This feature is especially useful when riding in a peloton, prompting rear riders to slow down in case of an emergency brake.

Auto-Sleep & Auto-Wake

Equipped with vibration sensing, the L308 can automatically enter sleep mode if stationary for 1 to 10 minutes ( settings adjustable). It will automatically wake up when you start moving. This feature can be turned off in the OnelapFit APP.

Ultra-Long Battery Duration

The L308 intelligent expression tail light boasts a maximum battery life of 50 hours (affected by custom settings and usage environment). Double-click the button to view the battery level for 3 seconds during use, and it will display the real-time battery level while charging.

Lightweight Design

The L308 intelligent tail light weighs only 23 grams, providing a lightweight and comfortable riding experience.

Easy and Fast Charging

The device features a Type-C charging port (charger not included) and charges to 80% in just 1.5 hours.
