Eletorot LED Bike Lights USB Rechargeable Bike Light Set,Waterproof LED Bicycle Lights, 3 Light Mode Options,Rechargeable Front Light Headlight and Tail Back Light

 These are a very neat design of rechargeable Bike Tail light that comes with its own short charging lead. The charging socket is a micro USB so most of us will have no problem recharging them anywhere where or not you have its own lead with you. when charging a green LED illuminates inside the light, once fully charged this changes to red.Operation is quite easy, a Long Press of about 3 seconds turns the light on then short presses cycle from full power to low power to flashing. As a flashing light is normally a turn indicator this mode should not be used although these days it is unfortunately legal. I have fitted the lights to the frame members sloping down to my rear wheel and also to the saddle bar stem, they look pretty effective in either position and seemed pretty secure although the smaller members I fitted then to were smaller than the 3/4 inch (20mm) diameter which is the theoretical minimum.To get to the charging socket you simply screw off the top of the light. I did find that when I took one of the lights back off my bike the light pulled out of its rubber strap probably because I was being a bit clumsy However it was a simple enough matter to work it back in again, it goes in through the smaller hole! If anyone needs help with this let me know and I will add a clip to my video showing how it is done.

I just bought these as winter is coming. It's dark out there and they fit nicely on to the rear of my bike. The light is good and the flashing mode saves battery power. They unscrew and charge via USB so you don't have to take the rubber clips off your bike. Very pleased.
