The audiences is probably hard to see whats happening if they wouldn't have used any spot lights and also without those lights, it would have been hard to film, but if they would have used lame spot light and added some smoke to there, then it would have looked little bit better, but the smoke fits better actually to dark forest than maybe to open field
Also if they would have placed blue lights to background area behind trees and those dry bushes, surrounding the road and add smoke, then it wouldn't show only the road in lighted area
