Let's hope this works as this will be my first tutorial. Ok, I've always wanted a quick safety light to wear around my neck when I'm working or out for a walk. So I created this using found objects.
Here is the parts all laid out. Very simple. I should point out that the switch shown is not the one I eventually used. I ended up using a SPST push button switch.
I took the green bottle and melted a hole in the lid to screw the switch into place.
I then soldered the battery onto the wire. The battery is a 3V watch battery that I picked up at the 99cent store (3 in a pack.)
