The lens has a plane rear side intended to be oriented towards a light source of a lighting module. A bulged front side (21) is oriented towards path to be lighted. Orientation units define a horizontal diametric axis (H) arranged parallel to the path. Sides define a diffusion zone (Z1) presenting an irregular state of surface that diffuses light emitted by the source to create a range of blurred power outage. The sides define a clarity zone (Z4) presenting a smooth and/or less diffusing state of surface as that of the diffusion zone to define a net power outage line in the range. |
