Our take on the USB Rechargeable LED Bicycle Taillight

A small seat-post taillight that straps on with Velcro and recharges over USB. It puts out about 10 lumens from a COB LED and runs from 5 hours on steady bright down to roughly 32 hours on the warning flash. The shell is PC plastic and the body is compact, so it suits commuters and casual riders who want a cheap, easy-to-move rear light. Against rivals it trades a big output and long steady runtime for many flash modes and a tool-free mount.

Questions and answers

How long does the battery last?
Rated about 5 hours on steady bright, 10 hours on low, 12 hours on flash and up to 32 hours on the warning flash. Runtime depends on the mode you pick.
How bright is it?
About 10 lumens. That is enough to be seen at night in town but weak for daytime riding or fast roads.
How does it attach to the bike?
A Velcro strap wraps around the seat post. It goes on and comes off without tools.
How do you charge it?
Through a USB port from the built-in rechargeable lithium polymer battery. No separate charger or batteries are needed.
Is it waterproof?
The shell is PC engineering plastic, but the listed specs do not state a water-resistance rating. Treat it as splash-resistant at best.
What shapes does it come in?
The light is shown in heart, circle and triangle shapes, all glowing red. Pick the shape you prefer.
Where is the USB Rechargeable LED Bicycle Taillight cheapest?
At Deal.ai, for $5.00, as of our latest check.
