what's not to understand D...
plain and simple... a point light will not light up the highway sections...
you'll need to use other things to give the impression of lights...
1- a flat emissive mesh that lies just above the ground to simulate the headlights shining on the ground... because the mesh is emissive it will be overlit... like a light is being shined on it...
2- two flat emissive meshes to simulate the headlights themselves...
3- a emissive (burn out) particle emitter to simulate the light rays...
connect em all to the car and you'll be ready to drive around all night long in the dark....
there's nothing more that a demo would show...
good luck...
