A signal line (6), e.g. for a loudspeaker or the like, includes a linear light element, such as a side-emissive light guide (16) illuminated by one or more LEDs (27, 29). A controller (28), e.g. housed in a jack plug connection (24) of the line (6), monitors the signal on signal wires (31) and modulates the LEDs (27, 29) accordingly through leads (32) and (33) and LED control wires (34). Thus, the electric line (6) may be illuminated so as to e.g. provide a light display to complement audio signals on the wires (31). An illuminated line (10) separate from the signal line (6) that connects with a music device output or input is also disclosed. |
