To insure that lamps which have a non-rotation symmetrical feature or strure with respect to aligned bases (e.g., a tipped-off exhaust or pumping stub) are placed in a predetermined preferred operating position when inserted into socket terminals (2a, 2b), the lamp bases are formed with stepped surface abnormalities (10a, 10b), for example, in the form of recesses or projections from a terminal engagement surface (8a, 8b) extending perpendicularly to the lamp axis (A--A); socket springs (2a, 2b) have matching surface abnormalities which interengage with the surface abnormality on the base, for example by being formed with ridges, or depressions. The lamp thus can be inserted in such bases only if the respective surface abnormalities on the lamp bases and in the socket terminals can engage. The lamp, however, can be used also with socket terminals which do not have such interengagement surface abnormalities, so that the lamps are universally usable with specific location-determining sockets, or with sockets where the position of the lamp must be determined by a user.

[ We claim:] [1.] A double-based lamp (1) having a preferred operating position, and defining a lamp axis (A--A), comprising the combination ofa light source includinga lamp bulb (3, 63, 73);at least one base (4a, 4b) secured to one end portion of the lamp;said lamp bulb (3, 63, 73) being radially n
[ We claim:] [1.] A double-based lamp (1) having a preferred operating position, and defining a lamp axis (A--A), comprising the combination ofa light source includinga lamp bulb (3, 63, 73);at least one base (4a, 4b) secured to one end portion of the lamp;said lamp bulb (3, 63, 73) being radially non-symmetrical with respect to said axis (A--A) and forming a radial asymmetry,said radial asymmetry defining said preferred operating position;two end portions (3a, 3b; 63a, 63b; 73a, 73b) extending from the lamp bulb along said axis (A--A); andlight emitting means (E1, E2; F) within said bulbsaid at least one base (4a, 4b) being secured to an end portion of the lamp bulb and having a first rotation-symmetrical portion; andwherein, in accordance with the invention,means are provided for determining said preferred operating position of the lamp,said preferred position determining means includinga surface abnormality (10a, 10b) formed on said at least one base (4a, 4b), located non-rotation symmetrically with respect to said axis (A) on a second other portion of said at least one base, and in predetermined relative position with respect to said radial asymmetry of the bulb.
