In combination with a vehicle headlamp assembly having a lamp body received between frame walls of a support frame and including pivot means on said frame walls and said lamp body aligned on an aiming axis about which said lamp body is adapted for rotatable adjustment relative to said frame, adjustment means located at one end of said lamp body for adjustably positioning said lamp body about said aiming axis, said adjustment means including a generally vertically orientated drive shaft having one end thereof provided with a head and rotatably journaled on said support frame above said lamp body, a housing rotatably supporting the other end of said drive shaft, a first bevel gear fixed with said other end of said drive shaft, a drive nut supported for rotation within said housing about an axis substantially normal to the axis of rotation of said drive shaft, a second bevel gear fixed to one end of said drive nut and having the teeth thereof meshing with said first bevel gear on said drive shaft, a threaded shaft extending through said drive nut and through both the forward end and the rear end of said housing and having the threads thereof engaging the internal threads of said drive nut, and one end of said threaded shaft nonrotatably connected directly to said one end of said lamp body whereby rotation of said drive shaft causes said first bevel gear to rotate said second bevel gear which in turn rotates said drive nut so as to cause longitudinal movement of said threaded shaft and adjustable positioning of said lamp body about said vertical axis.
