Got a pair of these lights off Amazon a few days ago. One is stowed away in the back of my car. The other one wound up being fitted to my snowblower. They were about $25/pair, and run on 4 AA batteries, or 2 18650 rechargable cells. USB charging, and there is a outlet to charge my phone. High power, low power, and strobe. I guess I can't resist adding doo dads to my stuff.
