Abstract
A vehicle headlamp can include a daytime running lamp with favorable light distribution characteristics. The vehicle headlamp can also include a headlight such as a low beam/high beam, a fog lamp, and the like. The vehicle headlamp can include a parabolic type reflector, a halogen bulb, and a driving circuit. The halogen bulb can include a first filament, a second filament and a shield member if necessary or desired. The first filament can be used as the above headlight, and the second filament adjacent the first filament can be used as the daytime running lamp. Because the second filament can be located at a closer position than the first filament with respect to the reflector, light emitted from the second filament can form a wider light distribution than that of the first filament. Therefore, the vehicle headlamp can provide a daytime running lamp with a favorable light distribution pattern along with the above headlight.
