These are BRIGHT. And i don't mean just visible. These are BRIGHT and i hope that even those that text and drive will see me.After i received them, I left the lights on till full battery discharge and they stayed on way longer that i will be on the road between charges. The charging took very short time and they are ready to go. The lights came with rubber and Velcro holder, very thoughtful.I've purchased from Magnus Innovations before and contacted their customer service in a few occasions. The products and the customer service are outstanding.Thank you, Magnus Innovations. ### ⭐⭐⭐⭐⭐ Great build quality, price point, and performance *by D***C on June 4, 2017* I'm a big fan of Magnus Products. The build quality has been uniformly outstanding. This little unit is no exception with a lower price point to boot. Just to be clear, I'm reviewing the S100 Bike Light, Powerful 100 Lumen White front headlight, NOT the red tail light. This is a bit confusing, as descriptions use the words tail light. Even the box this light came in says tail light. Be sure you are getting the red if you want red.Be sure to get the right light for your type of riding. I ride exclusively in urban settings, so a brighter beam headlight is not useful. In fact, overly bright headlights can blind oncoming traffic/bikes and make it harder to judge your position. I use headlights as a way of being noticed and to provide some road illumination. That said, I love the brightness/strobe options, which are perfect for my needs. I especially like the waterproofing. I've had other similar lights go bad in a downpour. the unit is sealed well and the usb port rubber stopper is much better than others' I've had. That said, the double insurance of a little waterproof electrical tape over the port provides me with absolute peace of mind. This is an especially good hack if for some reason you lose a rubber stopper.One caveat, easily remedied with a little DIY. I need to take the light off when parking in the city. This has resulted in scratches due to the hard plastic clip that rests against the handlebars/seat post. I attach a little Moleskin and then have a super-smooth contact between the light and the frame. The strong stretchy rubber fastener keeps it firmly in place.I did get the light on special offer of $8 in exchange for the review. Hope this is useful! ### ⭐⭐⭐⭐ Decent secondary light w/ flexible usage *by B***X on August 10, 2017* I like the flexibility the light offers, since I can put it on my bike or use the clip to attach it to my clothing, etc. So I've even used it camping. But for biking, its a bit dim/diffuse to use for a forward light, so it works better as a secondary or blinking light on a seat post or handlebars. It came with a small stretch band that the instructions claim can be used to attach to a helmet, though its unclear how that would be done. In fact, my main issue with the product was the instructions themselves. Not very clear or well designed, and I had some initial difficulty figuring out how to properly attach the light to my bike using its rubber stretch mount. I haven't used it enough to know how well it keeps its charge, but so far so good. --- ## 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.com.ar/products/136675232-s100-usb-bicycle-tail-lights-powerful-100-lumen-bike-tail](https://www.desertcart.com.ar/products/136675232-s100-usb-bicycle-tail-lights-powerful-100-lumen-bike-tail) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-18*
