A signal lamp whose frustoconical or frustopyramidal housing contains a square or cylindrical light emitting diode and has a rear wall which is completely surrounded by an endless rear edge portion of the sidewall of the housing. The rear wall constitutes or is disposed behind a plate-like carrier for the diode and one or more series resistors, and such rear wall can be bonded directly to the front side of the front wall of a switch box, control panel or the like. The front end of the housing has a square or rectangular aperture for the front wall of the light-transmitting envelope of the diode. The conductors which connect the diode to an energy source pass through one or more hollow projections which extend from the rear wall of the housing and through one or more complementary openings of the front wall. At least one of the projections can have external threads to mate with a nut which is located behind the front wall and urges the adhesive-coated rear side of the rear wall of the housing against the respective side of the front wall.

The combination of a support, such as a control panel, having a front side, with a signal lamp comprising a housing including a front portion having an aperture disposed in a predetermined plane, a rear portion, a substantially flat rear side located in the region of said rear portion and disposed in front of said support, and a carrier which is at least substantially parallel to said plane and to said rear side, means for securing said housing to said support, said securing means being disposed in the region of, and including an adhesive coating on, said rear side, a light emitting diode mounted on said carrier behind said aperture and confined in said housing substantially in its entirety, and conductor means connected with said diode and extending from said housing through said rear side and adhesive coating.
