Review on 🚴 Ascher USB Rechargeable Bike Light Set - Ultra Bright Front Headlight and Back Taillight for Road Mountain Cycling - Powerful, 4 Light Modes - Easy Install for Men, Women, and Kids by Nick Mitchell

I had my taillight on and charging a few nights ago when a three foot column of flame shot out of the unit with no sound or warning. It quickly shrank to about four inches in height, and after a few tries I managed to put the fire out. Thank goodness I was in the room at the time. At that time it was about one o'clock in the morning and he could very easily burn down my house with me and my family. My guess is that the lithium battery exploded, but there is no doubt that it was defective.
