Illuminable indicator and light engine therefor

1. An illuminable indicator comprising:

an opaque base;

a cover for the base, the cover having a formed design therein having a given circumference with an area defined by the circumference, the area provided with a reflector and at least the formed design being translucent;

mounting means formed in the base for receiving a light engine, and

a light engine fitted with said mounting means, said light engine comprising a thermally conducting body substantially symmetrically arrayed about a longitudinal axis, the body having a first end, a middle, and a second end, and at least two longitudinal passages extending from the second end to the first end;

said first end of said light engine being cylindrical and having a circumferential groove therearound and a lens fitted thereover, said lens having a primary part adjacent a plurality of LEDs and a plurality of legs extending therefrom, each of said legs having a terminus provided with a projection that engages said circumferential groove;

a planer area at the first end arrayed normal to the longitudinal axis;

a dielectric on the planar area;

electrically conductive traces formed on the dielectric; and

said plurality of LEDs secured to the dielectric and operatively connected to the electrically conducive traces.
