## Abstract

A cable interface is configured to mechanically and electrically connect to, via a plurality of piercing members, power-channel wires and a common wire of a ribbon cable. A lighting-element socket coupled to the cable interface is configured to receive a lighting element within and to provide electrical connection between power and common electrical contacts of the lighting element received and power-channel and common electrical contacts of the lighting-element socket. A channel selector conductively connected to the power electrical contact of the lighting-element socket is configured to select and electrically connect to a selected one of the plurality of power-channel wires via the power-channel contacting members.

## Claims

### Claim 1

A lighting-element socket connector for connecting a lighting element to a flat ribbon cable having a plurality of wires, the lighting-element socket connector comprising:
a cable interface configured to mechanically and electrically connect the socket connector to the flat ribbon cable;
a plurality of wire contacting members that includes a common contacting member and a plurality of power-channel contacting members located along a circle about the common contacting member at a common radial distance therefrom, each of the plurality of wire contacting members configured to pierce insulation of corresponding ones of the plurality of wires of the flat ribbon cable when the cable interface mechanically connects the lighting-element socket connector to the flat ribbon cable;
a lighting-element socket configured to receive a lighting element and to provide electrical connection between electrodes of the lighting element and contacts of the lighting-element socket, and
a channel selector configured to rotatably select and electrically connect a selected one of the plurality of power-channel contacting members to one of the contacts of the lighting element socket.

### Claim 2 (depends on 1)

The lighting-element socket connector of claim 1, further comprising:
indicia on an external surface of the lighting-element socket and/or the cable interface, thereby providing visual indication of which of the plurality of power-channel piercing members is conductively coupled to the power contact of the lighting-element socket.

### Claim 3 (depends on 1)

The lighting-element socket connector of claim 1, wherein the lighting-element socket is configured to receive a cylindrical Light Emitting Diode (LED).

### Claim 4 (depends on 1)

The lighting-element socket connector of claim 1, wherein the cable interface has a top member and a bottom member forming a clamshell structure that provides a passageway for the flat cable to pass therethrough.

### Claim 5 (depends on 4)

The lighting-element socket connector of claim 4, wherein the top member and bottom member of the cable interface have an open position and a closed position.

### Claim 6 (depends on 4)

The lighting-element socket connector of claim 4, wherein the top member is removably connected to the bottom member.

### Claim 7 (depends on 4)

The lighting-element socket connector of claim 4, wherein the passageway for the flat ribbon cable to pass therethrough is sized substantially equal to a size of the flat ribbon cable.

### Claim 8 (depends on 4)

The lighting-element socket connector of claim 4, wherein each of the piercing members extends into the passageway, so that when the clamshell structure is closed about the ribbon cable, the piercing members will pierce the insulation of corresponding ones of the plurality of power-channel wires and the common wire.

### Claim 9 (depends on 1)

The lighting-element socket connector of claim 1, wherein the lighting-element socket is a cylindrical lighting-element socket.

### Claim 10 (depends on 9)
