Frequently Asked Questions

Q: How does the brake sensing work?

A: The built-in accelerometer detects deceleration in real time. When you brake, the light automatically increases its flash intensity to signal drivers behind you — just like a car’s brake light.

Q: What does the intelligent light sensor do?

A: The ambient light sensor monitors surrounding brightness. It automatically activates the tail light in low-light or dark conditions and reduces output in bright daylight, extending battery life and ensuring appropriate visibility at all times.

Q: What is vibration wake-up?

A: The vibration sensor detects movement when you pick up or start riding your bike. The light powers on automatically — and enters sleep mode when the bike is stationary for a set period, conserving battery without any manual input.

Q: How long does the battery last?

A: The 3.7V 600mAh lithium battery provides up to 70 hours of runtime depending on the mode used. Flash modes consume less power than steady-on modes.

Q: How do I charge it?

A: Charge via the USB-C port using any standard USB-C cable. The reversible connector makes it quick and easy — no fumbling with orientation.

Q: Is IP66 waterproof enough for heavy rain?

A: Yes. IP66 is a professional-grade waterproof rating that protects against powerful water jets from any direction — more than sufficient for heavy rain, puddle splashes, and wet road conditions.

Q: What is the beam angle and why does it matter?

A: The 220° wide-angle beam means drivers, pedestrians, and other cyclists can see your light from almost any angle behind and to the side of you — significantly improving your safety at intersections and when changing lanes.

Q: What are the dimensions of the light?

A: The tail light measures 30 × 41 × 26 mm — compact and lightweight, it mounts discreetly to your seat post without adding bulk.
