[Dual-Light Design for Maximum Visibility] Featuring a sleek ''Circle + Strip'' LED layout and streamlined casing, this ultra-lightweight (0.06lb) tail light delivers 100 lumens of high-intensity illumination. Compact (4.13×1.18×0.98 inches) yet eye-catching, it ensures you’re seen day or night.
[Intelligent Safety Features] Go beyond basic visibility with brake sensing, light sensing, and motion detection. Brake sensing triggers a 5-second high-brightness warning when slowing down, alerting traffic behind you. Light and motion sensors auto-adjust power on/off based on surroundings. USB-C rechargeable and IP65 waterproof for relentless reliability.
[6 Dynamic Modes with Memory Function] Choose from steady, strobe, flash, warning, breathing, and meteor modes (up to 10hrs runtime). One-touch mode switching, long-press to power off, and auto-memory for your last-used setting. Tip: Press the right control button to toggle light-sensing mode (white LED flashes when active).
[Quick-Release Mounts] Includes saddle and seatpost brackets, compatible with road, MTB, hybrid, and commuter bikes. Secure "click-to-lock" installation prevents drops on rough terrain.
[Complete Package, Effortless Setup] Box contents: 1× tail light, 2× mounts, 1× USB-C cable, 1× manual. The auto sleep/wake function conserves power—activates in 30 seconds when idle, instantly relights when motion resumes. Ride smarter, stay safer.

Unclear instructions
The light sensing mode and brake sensing function are cool features (if they work?), but the instructions are converted from Chinese. It’s not clear how to enable/disable these features or know when they are set. Crossing fingers and hoping for the best.

The Best Taillight EVER
The features on this taillight are very impressive. At first I couldn’t figure out why when I turned it on it would turn off after about ten seconds, that’s because it has motion detection, so it shuts off to save energy. Its very bright and also senses daylight if you place it in that mode, while the brake light still functions. Or you can set it to come on continuously. The brake light is a game changer, it senses when you stop moving and brightens the lights. I pair it with two other taillights for extra visibility at night. I like having three taillights because what if the power runs out during a ride at night? You would not know that you’re riding without a taillight until you get to your destination. It’s unlikely that all 3 lights will run out of power at the same time so I have a backup system in place for safety. People that ride at night know what I mean.

Amazing at what it’s supposed to do!
Outstanding tail light! I ride 25-30 miles/ride in inner city Austin twice per week and the stop sensing feature of this light is fantastic to actually help others not only know that I’m there but also that I’m actually coming to a stop or slowing. Will be buying another for my other cruiser. CapTex Cruisers on Facebook if you’re in Austin.

PicnaRizer Bike Taillight
This is a great fit for every bike specially the ones that carry a flat/aeropost seatpost, since we don’t have your usual round seatpost is hard to find a taillight that is compatible with such bike. This light offers good quality clamps for the rails on your saddle also includes a seatpost strap if you happen to have your usual round post as well. it has over 6 modes you can choose from overall good light can’t complain about the price.
