4 - Draw the four circles on the base. Trace the edges of the dial.


5 - Fold the legs of 4 LEDs as shown.

6 - Bend the ends of LED wires as shown. This bend should allow the LEDs to stand up.

7 - Determine the "+" and "-" ends of the LEDs.
Note that LEDs are low-voltage and low-current devices.
They are easily damaged.

The "flat" spot on the plastic globe indicates the "-" lead.

8 - With tacks, place a piece of aluminum foil over the "-" (minus) ends of the LEDs
The aluminum piece is 1.5 cm x 9 cm. Notice that one end extends towards the end 
of the base.  This piece becomes part of the switch.
