1. A vehicle comprising:
- a first headlight having a first light source to project light outwardly from the vehicle, wherein the light projected from the first headlight is perceptibly dominant in a lower-frequency portion of a visible spectrum; and
a second headlight having a second light source to project light outwardly from the vehicle, wherein the light projected from the second headlight is perceptibly dominant in a higher-frequency portion of the visible spectrum, wherein the first headlight and the second headlight project light to simultaneously illuminate an area with perceptibly different-frequencies of light from different perspectives,wherein each of the first headlight and the second headlight provides a substantially homogeneous light beam, andwherein the first headlight is physically different than the second headlight.

Abstract
A vehicle includes a first light source to project light outwardly from a vehicle. The light projected from the first light source is perceptibly dominant in a lower-frequency portion of a visible spectrum. The vehicle also includes a second light source to project light outwardly from the vehicle. The light projected from the second light source is perceptibly dominant in a higher-frequency portion of the visible spectrum.
