Frequently Asked Questions

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

A: The built-in accelerometer detects deceleration when you brake. The moment braking is registered, the tail light instantly illuminates at full brightness for 3 seconds, maximizing your visibility to vehicles and pedestrians behind you — automatically, without any manual input.

Q: What is the difference between manual mode and automatic mode?

A: In manual mode, you control the on/off with a long press, and the brake sensing function remains active. In automatic mode, the light uses both a light sensor (turns on in low-light conditions) and a motion sensor (turns on when the bike moves, turns off after 30 seconds of stillness) — plus brake sensing is still active even when the light is in its dormant state.

Q: Is the X-TIGER WD-1001 tail light rechargeable?

A: Yes. The light features a built-in 420mAh rechargeable battery. Use only the included charging cable to charge it. Battery life ranges from 5 hours on constant mode up to 26.5 hours in ECO flash mode.

Q: What waterproof rating does this bicycle tail light have?

A: The X-TIGER Smart Tail Light carries an IPX5 waterproof rating, meaning it is protected against water jets from any direction — making it suitable for riding in rain and wet conditions.

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

A: The light mounts securely to the seatpost using the included bracket, ensuring a stable fit that stays in place on rough roads and trails. No tools are required for installation.
