Step 4: Mount the LEDs
My LED string had four different colored lights so i only selected the red and blue ones to light the eyes. To give space for the marble they had to be tucked fairly far back in the socket. I hot glued the front and back of them to secure them in place. Putting the skull in the pumpkin bumps it around a bit - so this hopefully avoided me getting the skull set and then knocking the lights out of the socket.
