Step 4: Testing

Picture of Testing
Plug in the battery compartment to the EL Panel plug.
Raise the battery compartment to about 15 degrees so that the mercury completes the circuit.
If you were successful, then the EL panel will have lit up once you plugged the battery compartment to the EL panel. 
If not, then open the cap back up and manipulate the tilt switch a bit more until it works.
Make sure to not break the mercury tilt switch because of MERCURY POISONING.
Repeat this step for the other completed EL panel.
There should be two options, whether it be blinking or just fully on. Make sure to switch this on to test it, tilt the battery compartment up and down. 
ALSO, THE CONNECTIONS FROM THE PACK TO THE EL PANEL IS FRAGILE. TRY NOT TO BEND IT A LOT OR YOU WILL NEED TO SOLDER IT BACK.
