Mr. Christmas Holiday Skaters Bulbs
 Kit includes : Two 6v e5 base light bulbs  with selected wattage for unit.
NOTE: SOME UNITS AT FACTORY DID NOT USE E5 SOCKETS AND DIRECTLY SOLDED WIRES  TO BULB , SO CHECK YOUR UNIT BEFORE ORDERING.
If that is the case you will have to de solder the wires from old bulb and resolder to new bulb which will take some electronic experience.
