European beam pattern tolerances






        For European type lamp to pass, with centres at 850mm or

        less from the ground, you must make sure:




        1. The angle of the beam to the left must be 23 degrees



        2. Beam image horizontal cut-off is between 0.5% and 2.75%


                below the 0% horizontal line




        3. Any ‘kick up’ is visible on the screen


        4. White light does not show in the zone formed by the 0%


                vertical and 0.5% horizontal line
