Bicycle light
Product fit
Built for riders who need a compact rear warning light without giving up runtime, charging convenience, or mounting flexibility.
Use this page as the Bicycle lights entry point before narrowing the bike platform, mount style, charging preference, lighting-mode mix, and packaging configuration you need for the final build.
Bright SMD LED output
The source boards emphasize bright SMD LED output with a round brake light and a slim vertical LED strip for a cleaner visual signature from behind.
USB-C rechargeable
The charging board keeps the USB-C story straightforward for daily riders who want a simpler charging routine and a rechargeable battery instead of disposable cells.
Two mounting options
Seat rail and seatpost mounting both remain visible across the supplied references, making the product easier to fit on road, gravel, and mountain-bike setups.
Application
The primary application board keeps the smart taillight grounded in a real bicycle setup instead of a generic accessory listing.
The cleaned English application board keeps the saddle, mount position, and red warning glow intact so buyers can judge scale, placement, and the rear-visibility story more quickly.

Lighting modes
Six lighting modes are rebuilt into a cleaner visual board that is easier to scan than the original marketplace panel.
Steady, breathing, quick flash, slow flash, warning, and guide-light modes are regrouped with runtime references so the page can show the mode range without relying on unreadable Chinese poster text.
Review mode optionsSelected parameters
The most useful values are surfaced early so the page stays readable.
Only the clearest product values from the supplied references are pulled forward here, leaving the longer specification board for buyers who need a fuller summary.
29 g body weight
The supplied parameter card lists a 29 g product weight, keeping the taillight in a lightweight class that suits performance-oriented bicycle builds.
USB-C charging
The rebuilt charging and controls boards both reinforce a USB-C charging layout for simpler daily use and cable compatibility.
IP64 water resistance
The parameter summary keeps IP64 visible as a practical weather-resistance reference for road spray, commuting, and mixed riding conditions.
25.4 x 31 x 105.8 mm
The cleaned size board keeps the width, depth, and height visible so buyers can judge fit below the saddle or against a compact seatpost layout.
500 m visibility
The source parameter image presents a 500 m visibility claim, which supports the product's warning-light positioning for night or poor-visibility riding.
Six lighting modes
Steady, breathing, quick flash, slow flash, warning, and guide-light modes are regrouped into a simpler English board instead of a tall marketplace poster.
Charging
USB-C charging and the rechargeable battery story are reframed into one tighter English feature board.
The charging board keeps the USB-C port and rechargeable battery message visible while cutting away the excess poster height that would otherwise slow down the page.
Confirm charging details
Mounting options
Seat rail and seatpost installation are both kept visible so fit decisions stay simple.
The overview board shortens the original story into a clearer choice between seat rail and seatpost mounting, which is more useful for bicycle buyers than a tall mixed-language poster.
Choose mount style
Seat rail install
The seat rail installation steps are rebuilt into short English instructions that remain technical without becoming crowded.
This step board keeps the line-art diagrams and numbered sequence, but the captions are shortened so the instruction flow stays readable on desktop and mobile product layouts.
Review rail install
Seatpost fit
The seatpost mounting view gives buyers a clearer everyday-use reference for road and commuter bikes.
A separate seatpost visual helps the page show the compact installed look on the bike frame itself, which supports quicker fit checks for riders who prefer strap-based mounting.
Review seatpost fit
Seatpost install
The seatpost strap instructions are also shortened into a cleaner English step sequence.
The translated instruction board keeps the mounting logic intact while reducing text density, which makes the install process easier to understand on a product page without zooming in.

Controls
The button, sensor, indicator, and charging-port locations are called out directly on the product body.
This rebuilt board uses short English labels only, which is enough for buyers to understand where the light sensor, mode controls, battery indicator, and USB-C port sit on the housing.
Review control layout
Operation logic
The operating instructions are regrouped into a cleaner two-block English board.
Instead of carrying over a dense block of marketplace text, the page keeps only the tap cycle, power-off hold, and light-sensor behavior that matter most during product evaluation.
Review usage flow
Product size
The size board keeps the body footprint visible without forcing the page to carry an oversized portrait poster.
Width, depth, and overall height are preserved in one cleaner English board so mount planning stays grounded in visible measurements rather than only in text bullets.
Review dimensions
Specification board
The broader product parameters are kept in one simplified English card set for buyers who need the full summary.
The specification board keeps weight, material, water resistance, visibility, size, charging port, and mode runtimes visible in a cleaner card layout that matches the rest of the site more naturally.
Review all specsWhere it fits
Common bicycle use cases for this smart tail light.
Road-bike rear safety
A strong fit for road riders who want a compact rear warning light below the saddle without adding a bulky commuter-style taillight.
Mountain and gravel bikes
The dual-mount setup also suits mountain and gravel bikes that may need either rail mounting or a seatpost strap depending on the frame and dropper-post layout.
Daily commuting
USB-C charging, multiple flash patterns, and the brake-sensing story make the product practical for everyday commutes and repeated low-light use.
