A universal electric indicator has a body, holding component (components) and light-emitting diode that are connected in sequence (electrically and mechanically). In parallel to the present light-emitting diode one more light-emitting diode is connected, in opposite (counter) direction with respect to the first one, and light-emitting diodes are placed in the bodies (body) that have contact ends and are connected to each other electrically (with a conductor). |
