Vehicle headlamp with means that can be distorted to absorb at least part of the energy from a choc

The headlamp (1), comprising a housing (2) containing a light source (3) and reflector (4) covered by a lens (5), incorporates deformable elements (14) between the lens and housing to absorb at least part of the energy of an impact. The deformable elements, made from a compressible material such as a foam with at least one in an annular or U-section shape, can be located between an inner mask (7) and the headlamp housing, or can form part of the mask itself.
