Frequently Asked Questions

Q: How does the smart brake sensor on the X-TIGER tail light work?

A: The built-in accelerometer detects sudden deceleration the moment you apply your brakes. When braking is detected, the tail light instantly switches to maximum brightness for 3 seconds, creating a clear, high-visibility warning signal for drivers and pedestrians behind you — no manual input needed.

Q: Can I use this bicycle tail light in the rain?

A: Yes! The X-TIGER Smart Tail Light carries an IPX5 waterproof rating, meaning it is fully protected against water jets from any direction. Whether you're caught in a downpour or riding through puddles, the light will continue to perform reliably.

Q: How long does the battery last on a single charge?

A: Battery life depends on the mode selected. In ECO flash mode you can get up to 26.5 hours of runtime. Other modes offer: constant on – 5 hours; breathing flash – 9.3 hours; comet flash – 10.3 hours; slow flash – 9.2 hours; and mixed flash – 11.6 hours. The 420 mAh rechargeable battery is charged via the included cable.

Q: How is the tail light mounted on the bike?

A: The X-TIGER WD-1001 is designed for seatpost mounting. It attaches quickly without tools and features a secure fit that won't shift or rattle, even on bumpy trails or city streets.

Q: What is the difference between Manual mode and Automatic mode?

A: In Manual mode, you control the light with the power switch and the brake sensing function is always active. In Automatic mode, the light uses both a light sensor (turns on when surroundings are dim, turns off after 30 seconds in bright light) and a motion sensor (turns on when the bike moves, turns off after 30 seconds of inactivity) — plus brake sensing remains active even when the light is in sleep/standby state.
