Circuit Troubleshooting

Having trouble with getting your LED circuit to work?

Try the following:

Make sure the positive side of the the light is connected to the copper tape or wire that is touching the positive side of the battery.
Make sure the battery is in firm contact with the battery.
Is the positive side of the batter touching the negative copper tape or vice versa?
Does the copper tape have any rips that are breaking the connection?
Are there any places where the positive side of the tape or wire touches the negative side without going through a light? This would be a short circuit.
Make sure the conductive edges of the lights are overlapping the copper tape enough to make a good connection.
Firmly press around the edges of the lights and anywhere the copper tape overlaps to make sure the connection is good.
Try a different battery.
