Abstract:
1. A light for use in a light string, said light comprising: a bulb; a filament in said bulb; a bulb holder carrying said bulb, said bulb holder having at least one hole therethrough; a tooth depending from said bulb holder; a first and a second Dumet wire extending from said filament inside said bulb through said at least one hole in said bulb holder to the exterior of said bulb holder; a socket carrying said bulb holder, said bulb holder removably seatable in said socket, said socket having an interior wall; a first and an opposing second electrical terminal carried by said interior wall of said socket, said first and second Dumet wires engaging said first and second electrical terminals, respectively, when said bulb holder is seated in said socket, said second electrical terminal having a hole formed therein; a spring shunt having a first and an opposing second end, said second end being inserted into said hole in said second electrical terminal so that said spring shunt is cantilevered across said interior of said socket toward said first electrical terminal, said tooth on said bulb holder being interposed between said first end of said spring shunt and said first electrical terminal when said bulb holder is in said socket so that electricity does not flow between said first electrical terminal and said spring shunt but rather from said first electrical terminal to said first Dumet wire and then to said filament and to said second Dumet wire and then to said second electrical terminal, said tooth allowing said spring to return resiliently into electrical engagement with said first electrical terminal when said bulb holder is removed from said socket, said spring shunt thereafter passing current directly from said first electrical terminal to said second electrical terminal and bypassing said filament; wherein said spring shunt is a coiled spring; and wherein said spring shunt has a central section having coils of a first diameter and said first and opposing second ends of said spring shunt have coils of a second diameter and wherein said first diameter is greater than said second diameter.
