A vehicle lamp for insertion into a vehicle bodywork opening comprising

• a lamp housing including an abutment adapted when the lamp housing is introduced from an exterior into the bodywork opening, to come to bear against a part of the vehicle,
• a sealing means which, in an installed condition of the lamp housing, sealingly closes the bodywork opening;
• at least one latching means adapted, in said installed condition, to engage behind an edge of the bodywork opening and operable to prevent the vehicle lamp from moving out of the bodywork opening;
• wherein the lamp housing includes first and second housing portions of which the first housing portion has an abutment and the at least one latching means and the sealing means is on the second housing portion;
• means for mounting the first and second housing portions displaceably relative to each other in an installation direction from a pre-assembly position into a final assembly position, and
• a bistable spring arrangement on the first and second housing portions and operable in the pre-assembly position to urge the first and second housing portions away from each other in opposite relationship to the installation direction and in the final assembly position to pull them towards each other in the installation direction whereby the sealing means is pressed from the exterior against outside surface of the vehicle bodywork.
