Frequently Asked Questions

Q: Why won't my bike tail light turn on when I first receive it?

A: Lithium-ion batteries naturally discharge during storage and shipping. If your tail light won't power on, simply charge it fully via the included USB cable (1–5 hours) before using it. Once charged, hold the power button for 3–5 seconds to switch it on.

Q: How do I switch between lighting modes on the LED bike tail light?

A: After powering on (hold the button 3–5 seconds), a single click of the power button cycles through the 4 modes: Steady, Slow Flash, Super Flash, and Cycle Flash. Another click after the last mode will power it off.

Q: Is this bike tail light waterproof enough for riding in the rain?

A: Yes! The tail light carries an IPX4 waterproof rating, meaning it is protected against water splashes from any direction. It is suitable for riding in light rain and wet conditions, though it is not designed for full submersion in water.

Q: What type of bikes is this tail light compatible with?

A: The Zpaxo LED bike tail light comes with a flexible silicone strap that fits most standard seatposts and handlebars, making it compatible with road bikes, mountain bikes, commuter bikes, and more — no tools required for installation.

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

A: Battery life ranges from approximately 3 to 12 hours depending on the lighting mode selected. Steady mode uses more power, while flash modes extend battery life significantly. The built-in smart full-charge cutoff helps protect the battery for long-term use.
