Abstract
A centralized lighting system particularly suited for aerodynamically styled vehicles is disclosed. The centralized lighting system employes a pressurized lamp preferably of a metal halide having quartz light guides merged into portions of its outer surface. The portions of the metal halide lamp that are not merged with the light guides may be coated with a diffusive reflective coating that substantially prevents light from being transmitted through the coating so that all of the light generated by the metal halide lamp is directed into and transmittd by the light guides. The transmitted light of the light guide is distributed throughout vehicle to supply the forward, rearward, and interior illumination needs of the vehicle.
