Abstract: An airfield marker light, e.g., for runways or taxi strips, comprising a casing (1) with a lower light source (4) and an upper, transparent cover plate (8) situated substantially in the ground plane. An abrasive resistant material, preferably in the form of particles partially embedded into the surface of the cover plate, protrudes upwardly from the cover plate exclusively in at least one dead zone (11, 12, 13), which does not emit any light. The hard material protects the cover plate (8) against mechanical abrasion, for example during snow-clearance by steel scrapers.
