A lamp unit housing for a vehicle, the lamp unit housing being adapted to receive and lock a lamp unit in a housing space of the lamp unit housing, the lamp unit housing comprising: - a first interior surface and a second interior surface at least partly defining the housing space, wherein the first and second interior surfaces are facing each other inside the housing space, - a first clamping means and a second clamping means, wherein the first clamping means is provided proximate the first interior surface and the second clamping means is provided proximate the second interior surface, and wherein each one of the first and second clamping means (103, 104) is moveable between an unlocking position for unlocking the lamp unit from the lamp unit housing and a locking position for locking the lamp unit to the lamp unit housing, - a synchronization member connecting the first and the second clamping means (103, 104), whereby the synchronization member synchronizes the movement of the first and the second clamping means (103, 104) between the unlocking position and the locking position - the lamp unit housing further comprising a clamping means moving member which is connected to at least one of the first and the second clamping means (103, 104), wherein the clamping means moving member is adapted to move the first and the second clamping means (103, 104) between the unlocking position and the locking position, wherein the clamping means moving member is provided outside the housing space proximate the first interior surface and is connected to the first clamping means, wherein the lamp unit housing further comprises a guide, such as a slot, which at least a portion of the clamping means moving member is adapted to be connected to and slide in when the clamping means moving member moves the first and the second clamping means (103, 104) between the unlocking position and the locking position, characterized in that, the guide extends between a proximal end and a distal end, wherein the proximal end is located proximate the first clamping means and the distal end is located distal from the first clamping means, whereby the portion of the clamping means moving member is adapted to be movable at the distal end of the guide between a first position where the clamping means moving member locks the first and the second clamping means (103, 104) into the locking position and a second position where the clamping means moving member is freely moveable in the guide. - a first interior surface and a second interior surface at least partly defining the housing space, wherein the first and second interior surfaces are facing each other inside the housing space, - a first clamping means and a second clamping means, wherein the first clamping means is provided proximate the first interior surface and the second clamping means is provided proximate the second interior surface, and wherein each one of the first and second clamping means (103, 104) is moveable between an unlocking position for unlocking the lamp unit from the lamp unit housing and a locking position for locking the lamp unit to the lamp unit housing, - a synchronization member connecting the first and the second clamping means (103, 104), whereby the synchronization member synchronizes the movement of the first and the second clamping means (103, 104) between the unlocking position and the locking position - the lamp unit housing further comprising a clamping means moving member which is connected to at least one of the first and the second clamping means (103, 104), wherein the clamping means moving member is adapted to move the first and the second clamping means (103, 104) between the unlocking position and the locking position, wherein the clamping means moving member is provided outside the housing space proximate the first interior surface and is connected to the first clamping means, wherein the lamp unit housing further comprises a guide, such as a slot, which at least a portion of the clamping means moving member is adapted to be connected to and slide in when the clamping means moving member moves the first and the second clamping means (103, 104) between the unlocking position and the locking position, characterized in that, the guide extends between a proximal end and a distal end, wherein the proximal end is located proximate the first clamping means and the distal end is located distal from the first clamping means, whereby the portion of the clamping means moving member is adapted to be movable at the distal end of the guide between a first position where the clamping means moving member locks the first and the second clamping means (103, 104) into the locking position and a second position where the clamping means moving member is freely moveable in the guide.
