Abstract
A reflector for a headlamp is divided into zones depending on the sizes of the light source images produced by the various parts of the reflector. Those parts of the reflector that provide smaller image sizes are used to supply light to the higher intensity parts of the road pattern. This allows greater control over glare and is particularly useful for headlamps having high intensity discharge as a light source. In one embodiment, a larger reflector is trimmed to be smaller and yet to retain portions that provide the small light source images.
