SIGEM Ultra Bright Bike Tail Light, Headlight, USB Rechargeable, Bicycle Flashing Rear taillight, LED Safety Warning Strobe Head Light, Also for Helmet and Backpack Max.120 Lumens

After 10 months of occasional weekend usage, my SIGEM Bike Tail Light poop out. It would not charge anymore. Prior to it pooping out, it was great. The light was bright and could be seen from afar. It was easy to mount on bike and simple to use and charge. I am very disappointed that it didn't last longer. I don't know if my SIGEM Bike Tail Light came with any warranty or not. Now I need to search for another brand.

Let me preface this with the fact that I'm an old guy, lol. Back in my younger years, lights for bicycles had nuts, bolts, wire...and lots of weight, lol. These lights are phenomenal. I work at night on my own schedule, so I ride almost exclusively after dark. I have three of the headlights (one for each fork and one on the handlebar stem) and a red taillight on my seatpost. They don't light the way forward as much as a focused beam would, but if you run the same routes daily, there aren't many surprises, so it's fine. They do provide enough light to see out front a decent way, but are GREAT for BEING seen. My handlebar light is always "steady on" and the other lights are on the fast blink. I fully charged one, and left it on overnight. It took slightly more than seven hours to almost completely discharge, and 48 minutes to fully re-charge. I love how easy these lights are to install, and that you can not only install them horizontally but also vertically. Additionally, I haven't yet read a review that mentions that they can also be pivoted slightly once installed to better help you see or be seen. I do a lot of camping, and actually plan on buying a few more of these to light my tent and such. For this price point, they are wonderful little utilitarian lights.

This light is very bright! I have the light mounted on the rear carrier and utilize the flashing red and alternating flashing red and white for heavy traffic situations. The mounting system provided with the light will enable you to mount the light to either a handlebar / stem front location, or a seat post rear location. Because I commute and utilize a bag on the carrier, I needed to mount the light to the very rear of the bicycle. Utilizing the light disconnect provided with the light, I fabricated a simple bracket to attach the light to my bike (See Photo). The light can easily be removed using the factory provided mount.

Had these lights for a few months and have used them on about 12 rides ranging from 45 minutes to 3 hours. Initially the battery lasted a long time. More recently the lights would lose power not even 40 minutes into my ride even after having just charged them. They are bright and have plenty of light modes. The small form factor is also quite nice. Battery life leaves me quite disappointed. I would be more understanding if I had been using it for a year and have cycled the battery through multiple charges. Anyway I can get replacements??

Very bright light. We use the flashing red for rear and flashing red/white for the front. They have about a 3 hour life more or less on high (not measured precisely). The don't take too long to charge. I think I got my money's worth for them. We use them day and early AM rides. I am seeing more and more lights in daytime and while I mocked my friends who are going this (initially) I have not swung over to being a use the all the time rider. Why not? None of us are in the TDF I don't think and if you are not either I think you ought to try it also.

Awesome brightness !Battery is weak. You have to charge it after 2- 2.5hrs of use. That’s a nuisance and charging takes about 3hrs.

I bought this for use on my wheel chair. The light is brighter than my last one, but also more options to choose from. Makes me feel safer when I have to use streets to get around on.Also easy to mount, no tools needed.

exactly as I expected, and comes with x2 colours - Red and bright white!. I'm using this one as a tail light and I want my riding colleagues not to get blinded by the light - so mostly use a low blink on red for now.
