Thread: LED help

Tweet

I salvaged a couple of these from an animated ghost that fell down and broke
and was wondering if there was a way of resurecting these babies. Any info is appreciated !
P.S. Sorry about the picture size!!!

You should be able to.

Were they bi-color LEDs?
What powered the Ghost? 1 9V, 2 AA?
If 2 AAs, you would probably be safe with 3V, if 9V you would really need to find out what the output was to the LEDs, and knowing that would help extend the life of them. If there is no way to find out the power output, start with a AA and keep adding them until you get illumination. Keep in mind LEDs will not power if you have the voltage reversed so if you don't know which lead is positive and which is negative, test the batteries both ways. LEDs should be protected from reverse voltage.

The two dark wires look like enameled copper wire, so you will probably need to sand the ends to expose the copper for testing.
