How To: LED Eyeballs

One of the best ways to dress up any off-the-shelf skeleton, ghoul, or generic spooky creature is to add a pair of LED eyeballs.  It creates a very dramatic effect for very little effort, and it is a simple way to make your haunt stand out.

To start, you’ll need to collect the parts.

  • two eyeball blanks (roll-on deodorant balls)
  • two “super bright” LEDs (any color)
  • some speaker wire
  • two AA Batteries
  • a battery connector
  • a skull
In our example, we used a soldering iron to connect the wires.  If you don’t have a soldering iron, you can twist the wires together and wrap the connections in electrical tape.  However, if you’re planning on building any props in the future, now is the time to buy a soldering iron and to learn how to use it.

First, drill a hole in each of the eyeballs.   The holes need to be the exact size of the LED bulbs.  Then, stick the bulbs into the holes.  Easy, right?

Next, comes the wiring.  Connect the LED to your wires using the soldering iron.  Don’t forget to put insulation around each of the wires before you solder.  This step will save you from shorting out the circuit when you connect the battery.  Then, heat the insulation to shrink it.  Repeat for the second eyeball.
Then, drill a hole in each of the eye sockets of the skull making the holes just big enough to thread the wire through.  WARNING:  Don’t just drill straight back through the back of the skull.  Your best move is to drill down so that the hole comes out somewhere around the neck.  This placement will make it much easier for you to hide the wires.
After you’ve threaded the wire through the skull and gotten your eyeballs positioned the way you want them, it’s time to attach the battery connector.  First, make sure your wire is the proper length.  You’ll need to think ahead to where you are going to hide the batteries.  Then, solder the wire to the connector.

Finally, snap the batteries in place and check out your work!
