a second reflector disposed within the second light housing and forming first and second divergent inner walls of the second light housing, each of the inner walls being substantially free of openings therein so as to form an unbroken surface from which light may be directed, the first wall extending towards the longitudinal centerline of the vehicle and the second wall extending away from the longitudinal centerline of the vehicle, each of the inner walls including a curved portion adjacent the light-emitting element, the curved portion transitioning to a substantially non-curved portion;
a first light-emitting element disposed in the housing in front of the first reflector, the curved portion of the first reflector being disposed adjacent the first light-emitting element; and
a second light-emitting element disposed in the housing in front of the second reflector, the curved portion of the second reflector being disposed adjacent the second light-emitting element;
each of said first and second light-emitting elements and a respective one of the first and second reflectors cooperating to establish a beam pattern of light to be projected therefrom, said beam pattern intersecting the longitudinal centerline of the vehicle and extending outward and rearward therefrom past a line transverse to the longitudinal centerline of the vehicle and extending through a rearward end of the light housing, the first and second light-emitting elements together effectively illuminating an area greater than 180°
about the front of the vehicle.

Abstract
A headlight and sidelight assembly is provided for an off-road vehicle having a front enclosure. The front enclosure has a front end face lying substantially in a plane disposed substantially perpendicular to a longitudinal axis of the vehicle and first and second side faces. First and second light housings are disposed at the intersection of the end face and opposite side faces and are each open toward a side and front of the vehicle. First and second reflectors are provided in the housings and form divergent inner walls of the housings. Light emitting elements are disposed in the housings in front of the reflectors, each projecting a beam pattern of light intersecting the longitudinal centerline of the vehicle and extending outward and rearward therefrom past a line transverse to the longitudinal centerline of the vehicle and extending through a rearward end of the light housing, so that the first and second light-emitting elements together effectively illuminate an area greater than 180° about the front of the vehicle.
