Side flashing lamp

A side flashing lamp for fitting in the cover cap of an external rear view mirror for a motor vehicle, comprising

• a lamp housing having an elongate light exit opening which in the installed condition extends from an outward side of the cover cap, which is remote from the vehicle, substantially horizontally towards the vehicle,
• at least one group of light sources which are arranged distributed at least substantially uniformly along a line and which in the installed condition extend at least substantially horizontally over the length of the light exit opening,
• at least one optically active device which focuses the light of the at least one group of light sources in a main radiation direction which in the installed condition faces substantially in the direction of forward travel of the vehicle,
• at least one elongate light guide which is at least substantially of the same length as the line along which said group of light sources extends, said light guide extending parallel to said line and having a first end which is towards said vehicle in the installed condition on the vehicle, and a second end remote from the first end, and
• at least one further light source positioned for coupling of the light of the at least one further light source into said first end of said light guide which is thereby operable to pass said light at least almost completely to its second end where said light is emitted in a direction extending substantially inclinedly rearwardly with respect to said direction of travel,
• wherein the light guide is of a substantially bar-shaped configuration, and
• wherein said optically active device is a converging lens of a bar-shaped configuration.
