I've had this design in my repertoire for many years. The Cheers Collection is especially fun. And I quote Dorothy Parker (1893-1967) "1 Martini, 2 at the most, 3 I'm under the table, 4 I'm under the host" Dorothy comes from my original neck of the woods- Longbranch, New Jersey!
For your convenience an optional automatic sensor is available which will turn it on when the room is dark and off automatically when it is light. A 4 watt bulb is also included.
