pro-beam lighting (in a tunnel)

lighting where the light falls on objects in the same direction as the traffic

NOTE Pro-beam lighting is characterized by using luminaires that show a luminous intensity distribution that is asymmetric in relation to the C90-C270 plane (the plane normal to the direction of the traffic), where the maximum luminous intensity is aimed in the same direction as the direction of the traffic.
