A light pylon (1) has a post (2) having a vertical axis (4); a head (5) located at the top end of the post (2) and defined by two arms (9a, 9b); a light mounting frame (6) selectively attachable to the head (5) and movable in a first direction (D1) parallel to the axis (4); and a fastening device (22) for connecting the head (5) and the light mounting frame (6); the fastening device (22) being defined by first connectable elements (31) and second connectable elements (32); the first connectable elements (31) extending parallel to a second direction (D2) perpendicular to the first direction (D1); and the second connectable elements (32) extending parallel to a third direction (D3) perpendicular to the first direction (D1) and forming an angle of other than zero with the second direction (D2). |
