Locate your light at the same location as the camera, with a slight 
offset if you want.
Make it a spot_light.
Spotlight have a point_at parameter, make it the same as your look_at. 
point_at default to <0,0,0> if you don't set it.

#declare Light_Offset = <0, -0.5, 0>;
Camera{Cam_Location look_at Somewhere}
light_source{Cam_location + Light_Offset
    rgb 1
    spotlight
    radius 5
    tightness 40
    point_at Somewhere
  }
