Abstract
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.
