Review on D& USB Rechargeable Bike Light Set: Front Headlight & Rear LED, 4 Light Modes, Water Resistant IPX4 by John Love

This pair of bike lights seemed like too big a bargain but they actually work. They have multiple settings - different brightness and a few different turn signal settings. They charge via USB, which is much better than rechargeable batteries. They have an elastic band to attach to a handlebar or something that works but is a bit tight and uncomfortable. The front light doesn't work very well on a bike because it interferes with the brake line housing. My biggest complaint so far is the tail light, which quite often stops working. It may be a bad battery I suspect. Both flashlights are identical except for the color of the lenses. The front light blinks at least 3 times in half an hour, but I've come to work a couple of times and noticed that the tail light is off. Maybe it has a fault in the circuit or maybe a weak battery. I'm still giving it four stars because the headlight works great and is more important to me and the pair was cheaper than most headlights individually. It would be nice if the tail light worked too.
