Although it is different model, it still impress me that the light is very bright. Very easy to install, just hook. I will highly recommend this for biker. Let’s ride with safety. ### ⭐⭐⭐⭐⭐ Perfect for road riding *by J***E on Reviewed in the United States on August 1, 2018* Visible, easy to mount, lightweight, chargeable ### ⭐⭐ Failed attempt *by A***H on Reviewed in the United States on July 11, 2018* Idk where ppl are saying its 5 stars. It is Bright and it works, yes. It charges and seems to be made decently. The mount is firm and made of thick decent non scratching rubber. It does the SOS 45 degree angle thing. It has bright and dim settings and the three different modes. So why do I rate 2 stars? Because the motion sensor doesn't work right so it is ALWAYS on brake mode. Once in a while it'll flash on the mode it is supposed to but it doesn't detect speed decrease or increase. It just always stays in braking bright light mode. Not actually bad in low light conditions but it isn't working as described or intended. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/102386401-ampulla-motion-sensor-bike-taillight-usb-rechargeable-ultra-bright-bike](https://www.desertcart.tn/products/102386401-ampulla-motion-sensor-bike-taillight-usb-rechargeable-ultra-bright-bike) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-30*
