A luminous indicator of transmitters for radio receivers, characterized in that the frontal plate of the dial has a transparent elongated strip that is constantly illuminated by a central lamp. Parallel to this strip and between it and the outer one that bears the symbols of the scale of the dial, an opaque sheet of vertical sliding plane moves, which blocks a certain length of the transparent strip at will, the vertical mobile line being the boundary between the area opaque and luminous of the transparent strip the one that defines the tuned station, that is the one of the scale that agrees with the mentioned line.
