This is my first Instructable and since I don't want to be left in the dark I decided to enter the Flashlight Contest with a flashlight that is both rechargeable and waterproof.
Step 1: I need to start somewhere.
I started of by gathering all the parts I needed. In this case I had most of the part except the two threaded pipe fitting and the 12V bulb. I got those at my local hardware store. I also needed a threaded end cap but they had none in stock. The bulbs are just like the regular downlight bulbs but they do not heat up like the regular bulbs, the use less energy and last longer. They will also withstand bumps and knocks better. I sourced a 12V rechargeable battery from a old RC car.

50mm Threaded PVC Fitting x 2
Threaded PVC end cap Fitting
Smallish Toggle Switch
12V 24LED Downlight Bulb (They are available in different colours)
12V rechargeable battery
Small piece of foam
Tape, Cable ties and heat shrink
A 9V battery will also work but the the light won' t be that light or battery holder may also work if you can get it to fit and it has enough power example 8 1.5V AA batteries.
Diagonal pliers (I had to look this one up, I know them as a Side Cutter - http://en.wikipedia.org/wiki/Diagonal_pliers)
