Quick Fixes

If your LED bulb is not lighting up, try the following fixes: 

  1. Make sure that your conductive dough pieces are not touching. To help prevent this, place a piece of insulating dough between the conducting dough. 
  2. Check that the LED terminals are paired with the correct battery terminals. The longer LED terminal pairs with the red battery terminal, and the shorter LED terminal pairs with the black battery terminal.
