NightEye...
Try making the lense of the light from rippled glass with a fairly high IOR... just like real lenses on lights...
and remember to put a chrome hemisphere as the reflector behind the lense...
also put a secondary reflector inside, in between the two so that the reflections are more complex... if you email me i'll send you a copy of my golf model to see how they're done
