Abstract

The light display circuit employs at least two adjacent light elements, each being connected via a coupling diode with a respective signal output. Each of the light elements is also connected to at least one further signal output via respective coupling diodes, with one, or two separate, resistances in series with the coupling diodes for the additional signal outputs. Pref. the two light elements are used for fivve signal outputs two couled via diodes to one element one coupled via diodes to both elements and the other two coupled to one element via a diode and to the other via a series diode and resistor.
