The W999 front bicycle light combines 9 LEDs with reflectors and 21 SMD LEDs to provide cool white low and high beam lighting. It has 7 lighting modes, a built-in electronic horn, and a handlebar remote with separate buttons for the light and horn. The digital display shows the battery charge percentage, while the USB-A port allows emergency phone charging.

The light attaches to the handlebar using a dual-clamp mount and plastic adapter inserts. The built-in rechargeable battery provides 2–8 hours of runtime, depending on the mode, and charges via USB Type-C. Charging a phone reduces the available lighting runtime.
