1. A light unit for use in a light string, comprising:

  • a socket;

    a bulb having a peripheral side wall and an elongated lower separator protrusion offset toward said periphery and a light source with lead wires located along the sides of said lower portion and a separator separately insertable support switching body interposed between the bulb and socket and separate and removable from the socket, said separator including a switch member in said body having a pair of spring terminals; and

    having two or more conductive terminals lower terminal ends and adapted to receive the bulb and said lead wires on said bulb, wherein the switch member a pair of peripheral sidewalls defining a space therebetween, and a first terminal spanning more than half the distance between the sidewalls and a second terminal spanning at least the remaining space therebetween, so that, in their relaxed state, the terminals touch, and adapted to cause the pair of spring terminals to contact one another to form an electrical short circuit across the pair of conductive terminals when the bulb is at least partially removed from the socket, and wherein at least one of said terminals is configured to flex in response to contact with said protrusion on the bulb, thereby breaking the contact between the terminals.
