We've all seen it somewhere, a lightbulb above someone's head when they get an idea, whether in a tv show or movie. Well, I will show you the same effect!
2 AA batteries (depending on your LED)
battery pack (or you could wire it up yourself)
LED or even flashlight bulb.
To retrieve a flashlight bulb, just unscrew the top of a flashlight, then take the lense and reflectors off the top so you can take the bulb. I got my bulb from an old IDon'tKnowWhat that lit up when it was turned on. I ripped mine off the PCB, but you can buy a bulb from Radioshack.
Step 1: Bulb Prepping
Take out all that wiring and glass so you have the empty bulb. When you have cleared all broken glass, wiring, and other components, hit the bottom cap with scissors to make a hole. thats where your wire will go. You may have to move around the scissors in the hole to make it bigger.
The reason we took off the bottom cap is that all that wiring inside can mess up the LED and we need to get rid of it all.
Step 2: Wiring it up
Finally it's almost ready! Now put your LED (off please, don't kill the batteries) and carefully put it through the opening we made earlier on the bottom of the bulb. We're good to go. Now lets take it farther...
Step 3: The Hat
First, Glue or tape the bottom cap/sleeve to the rest of the bulb. Then you are ready for attachment to the hat. Hot glue the bulb and battery pack in a convenient place for you to carry on the hat.
I placed the bulb smack in the middle, and instead of concealing the batteries, I put them in front for show.
Please post your own version!!!!!!! Or atleast comment!!!!!!!!!!!!!!!!!
