One time, I stole the barricade and took it apart and save the flasher assembly. The one I had was powered by 2 6-volt lantern battery and it flashes once about every second or second and half. Sadly, I no longer have the flasher
I wonder if this one was stolen. My English teacher told me that someone just randomly came into his classroom with this light. xD He kept it. Since he retired this year I got to keep it.
I wonder where that guy got it...
