An indicating lamp unit or the like is mounted on a wall of a motor vehicle body through mounting pins carried by the lighting unit and carrying retaining means which fit in holes formed in the body wall. Each mounting hole in the body wall is of banjo shape, having a first part through which the retaining means can freely pass and a narrower second part which hold the retaining means securely when the lighting unit is moved sideways. Each of the said retaining means comprises a retaining ring having a peripheral groove defining a middle zone bounded by a pair of generally transverse flanks, which engage on either side of the narrow second part of the mounting hole so as to retain the retaining ring to the wall against movement in either longitudinal direction.
