Animal deterring automotive light

Large animals, like deer, moose and kangaroos, crossing roads cause a large amount of accidents resulting in physical damage, injuries and deads. Some successes have been reported in deterring such animals from roads using mirrors set to reflect the cars' headlights towards the roadside. In deserted areas (where this problem is most manifest) it is impractical and not affordable to mount large amounts of mirrors along the road. Besides, light sources designed for this purpose (eg. in spectrum and flicker frequencies) are expected to be more effective in deterring animals than the standard automotive headlight lamps. Therefore an automotive light is proposed which emits a specific animal deterring light into the roadside at a certain range besides or in front of the vehicle. Exploiting the differences in eye sensitivities between relevant animals and humans this light can be optimised to be least obtrusive to humans. For some animals it may turn out that the light from the standard headlights itself is attractive, luring them onto the road. In those cases, the spectrum and, or flicker frequencies of the headlight can be engineered to be unattractive or even deterring to animals but still be acceptable to humans.
