ABSTRACT:
A signalling light according to the invention has a concave reflector with a substantially cylindrical lamp holder for an electric lamp. The position of the lamp holder can be adjusted from inside the reflector. The lamp holder is connected to the reflector so as to be rotatable about its axis. Means which can be manipulated from inside the reflector fix the lamp holder in any adjusted position.
The construction of the signalling light makes it possible to position an asymmetric light source in the reflector in such manner that an optimum light beam is obtained.
