A light engine having a housing for containing a light emitting diode, the housing having a distal side and a shank projecting from the distal side. The shank is passed through a panel to be on the distal side of the panel while the housing is on the proximal side. A first shank seal outside the shank seals the exterior of the shank at the distal side of the panel. A second light guide seal at a cap at the distal end of the shank seals the cap and the shank around a light guide rod extending into the cap.
