An accent lamp () having a solid state light source (), such as LEDs, is attachable to a rear surface of an automotive headlamp () opposite the light-generating capsule (). Accent lamp () has first retaining member (), such as a clamp, formed above printed circuit board () on which LED () is mounted. Headlamp base () defines light passageway (), formed as a light guide (), extending from outermost peripheral surface () to an upper surface () on which lamp capsule () is retained. Accent lamp () is readily detachably mounted to headlamp (), preferably by resilient first and second retaining members (), and, when mounted, can be biased to promote optical coupling of light source () to light guide ().

Vehicle headlamp and light-injecting accent lamp combination and method

Vehicle headlamp with light passage

A method of providing accent ornamental illumination to a lamp of a motor vehicle comprising providing an accent lamp comprising a housing and a light-emitting device disposed within the housing; mounting the housing to an exterior surface of the lens cover of the vehicle lamp; and arranging the light-emitting device such that, when the housing is mounted to the exterior surface of the lens cover of the lamp, light emitted from the light-emitting device passes through the lens cover from outside the lens cover towards a lamp reflector of the vehicle lamp and illuminates the reflector. A motor vehicle lamp combination comprising, in combination, a motor vehicle lamp and an accent lamp also provided wherein, when the accent lamp is mounted on a lens cover of the motor vehicle lamp, light emitted from the light-emitting device is directed towards the reflector.

Lamp

An automotive headlamp bulb provides the two light or three filament sources in a single bulb. One source may be used to generate a standard headlamp beam, while the second source may be used to generate an augmenting side beam in response to a turning signal. A similar third filament may provide an augmenting beam to the opposite side, or farther to the same side. The single bulb eliminates the need for a second bulb, or a second reflector in an advanced headlamp system with turning light augmentation.
