PCT No. PCT/SE79/00070 Sec. 371 Date Nov. 30, 1979 Sec. 102(e) Date Nov. 28, 1979 PCT Filed Mar. 28, 1979 PCT Pub. No. WO79/00849 PCT Pub. Date Nov. 1, 1979.A protective device for a ground-deposited light is disclosed. Such a light, e.g. a guide-light for airfield use, generally includes a housing (2) having a cover (3) provided with an opening (5) for letting out light rays from a lamp (4) within the housing. To protect the lamp from rain, snow and dirt the opening is sealed by a translucent material. To protect the translucent material from mechanical influence grains of a harder material than the translucent material are partly embedded therein.
