Key Features

• Auto Brake Sensing: Built-in accelerometer detects deceleration instantly — both in Auto and Manual modes — and triggers a 3-second high-brightness burst to alert vehicles and pedestrians behind you.

Frequently Asked Questions

Q: Does the X-TIGER WD-1101 bike tail light automatically detect braking?

A: Yes! The smart brake sensing feature uses a built-in accelerometer to detect deceleration in both Auto and Manual modes. When braking is detected, the taillight instantly enters a high-brightness state for 3 seconds, significantly improving your visibility to vehicles and pedestrians from behind.

Q: How long does the battery last, and how do I charge the X-TIGER tail light?

A: The built-in 420 mAh lithium-ion battery provides up to 9 hours of runtime at maximum brightness on a full charge. Recharging is simple — use the included Type-C USB cable connected to any USB power source such as a power bank, laptop, or wall adapter. Always use the provided cable to ensure safe, optimal charging.

Q: Is the X-TIGER bike tail light truly waterproof for riding in the rain?

A: Absolutely. The WD-1101 carries an IPX6 waterproof rating, meaning it is fully protected against powerful water jets from any direction. You can ride confidently through rain, puddle splashes, and wet road spray without worrying about damage to the light.

Q: How do I mount the X-TIGER tail light to my bicycle?

A: The light comes with saddle mounting brackets and adjustable silicone straps, allowing quick and tool-free installation on either a seat tube (seatpost) or saddle rail. The mounting hardware accommodates most standard bike seat post diameters and can be swapped between bikes in seconds.

Q: What are the 6 light modes and how does Auto mode work?

A: The six modes are: Always On, Fast Flashing, Slow Flashing, Rhythmic Flashing, Breathing Flashing, and Energy-Saving Flashing. In Auto mode, the integrated light sensor monitors ambient brightness — it switches the taillight on automatically when surroundings are dim and powers it off after 30 seconds of bright conditions. It also auto-powers off after 30 seconds of no movement and wakes again when motion is detected, maximising battery life on every ride.
