5 minute safety light

I've always wanted a simple light that I could wear around my neck while working or walking at night. Flashlights can be too heavy or unwieldy and I could never get ahold of those head mounted lights to work very long. So with found parts and a few minutes of time, you can build this light.

By the way, I'm entering this into the LED contest so please vote for me!!

Step 1: Step 1: Materials

Here is the parts laid out. Not shown is the chain that I used to wear. In later versions, I used a zip tie to hold the chain and black spray paint to mask the pill bottle cap. Also note that the switch shown is not the one I ended up using. I used a SPST push button switch.

the shack sells a coin cell battery holder that will fit in the housing. Good way to repurpose "medicine" bottles.

Thank you for the comment. It's amazing that I still can't find any other colors. I'd love to get my hands on some red ones. The blue one is my favorite though.

I am never a fan of soldering directly to a battery, as this can burst one of those little coin cells really easy due to the heat. A good alternate method would be to use a conductive glue or just electrical tape.
Overall though, I really like the simplicity of your desing. This would be a good thing to make up just before kids go out for Halloween, or running before/after daylight hours.

Thank you. True, I normally don't solder directly to a coin battery but I couldn't figure out how to mount it into a holder and still make it fit in the container. Thanks for the compliment. It really does work. I've kept myself from being run over at least twice since I've started wearing it!
