Review on SIGEM Bike Light Set: Ultra Bright, USB Rechargeable LED Front Headlight, Rear Taillight, and Helmet Light for Easy Installation. Waterproof Bicycle Head & Tail Lights (3 Pack). by Eli Saumell

Looks good quality. Everything works out of the box. The design looks good. Fasteners are good. The lights appear bright enough to be used for their intended purpose. I'll have to use them for a while and see how they hold up. I will update if anything goes wrong. Update: Well, after a few overnight rides, everything is working fine. Headlight and taillight are bright enough. The only downside I found was that the taillight only lasts about 2.5 hours on a full charge. For me personally this is not a problem as I can simply charge it before every ride. But if you're going to use it for longer trips, keep that in mind.
