Abstract
A vehicle headlamp system having optical reflector, lamp capsule, and gasket is disclosed. The vehicle headlamp system uses surfaces formed as part of the optical surface yielding located light source. As a result, the light source is more accurately positioned with respect to the reflector, and a more accurate beam pattern is formed. The lamp capsule is assisted in its location by a spring to force the capsule in proper location. The headlamp system no longer uses an O-ring to provide location, but an improved flat resilient gasket provides a sealing and locking force to maintain proper face to face coupling. The preferred lamp capsule uses a cup to shield light reflected from the press seal. The preferred lamp capsule uses a cup, and pedestal system mounting providing five axes of light source positioning. The preferred lamp capsule uses a clip coupling to join the light source holder to the plastic base.
