Abstract: A fastening arrangement for mounting a lamp or a headlight in an opening of a vehicle wall part in which there is at least a partial overlap between the lamp or headlight and the edge of the opening and the lamp or the headlight can be fastened to a second vehicle wall part by at least one fastening device pivotally connected to the lamp or headlight so that the lamp or headlight can be retained in the opening in the first vehicle wall part. This makes it possible to fasten lamps or headlights, such as additional brake lights or side indicator lights, between two vehicle wall parts without any need for accessibility between the vehicle wall parts. As a result, it is possible for such lamps to be mounted in vehicle wall parts which border cavities in vehicle parts.
