Step 4: Directing The Light (optional)

Building the light dome thing.

1.Use a medicine cup and mold some shiny tinfoil around the bottom to form a cup.

2.Then wrap some tape around the tinfoil while it is still on the medicine cup to strengthen it.

3.Take off the new tinfoil cup thingy and poke a small hole in the bottom.

4.Insert the light into the hole and tape it all together so it looks like the last picture.

(note this step isn't needed it just directs the light more if that's what you want)

Step 5: And your done.

To Use it:
Simply push the striped wire sticking up onto the negative contact of the 9v.

Problems/Solutions:

Burns out sometimes: Make another?

Doesn't turn on: Try twisting the bulb while holding the contact down. Maybe the wires aren't touching the contact. Un-tape and try again.

Fun idea. So are these from a string of 110V AC xmas lights? I've got a bunch of strings of these with half the lights not working; I'll buy a case of 9V batteries and my Christmas shopping is done for the next 2 years! :) Thanks for posting.
