A headlamp illumination source that switches from a first configuration conforming to on-road illumination standards to a second configuration that does not conform to on-road illumination standards. The switching is preferably controlled by a wireless signal but in some embodiments the switching can be controlled by a hard-wired signal or by a switch proximate the illumination source itself.

A fan system for a headlight of a motor vehicle, wherein the fan system comprises a fan mount which is designed to be fastened to a housing of the headlight and comprises at least two bayonet guides and comprises a fan which comprises at least two bayonet elements, wherein the bayonet guides and the bayonet elements form a bayonet joint by means of a plug-in movement of the fan into the fan mount in an axial direction and a rotational movement of the bayonet elements into the bayonet guides in a rotational direction, wherein each of the bayonet guides is formed between a main body of the fan mount and a bayonet arm of the relevant one of the bayonet guides, wherein each of the bayonet arms is fastened to the main body and is spaced apart from the main body in a direction counter to the axial direction.

The invention relates to an optical module comprising a radiator having one or more heat dissipation surfaces, a fan capable of conveying air onto the heat dissipation surface, and a light source supported by the radiator. The principle characteristic of a module according to the invention is the radiator is formed from folded metal sheets, the fan being secured to the radiator by securing means provided in the folded metal sheet.

A vehicle headlight system can include a headlight controller and a lamp unit incorporating a high beam module, which can emit favorable marking lights while the headlight controller associates each of a shading driver and a swivel structure with a shading width setter and a swivel setter, respectively. When a forward vehicle does not exist in a forward direction, the headlight systems can provide favorable light distribution patterns by overlapping the light distribution pattern projected from the high beam module with each of light distribution patterns for a high and low beam. When the forward vehicle exists, the headlight system can prevent the lamp unit from emitting a glare type light to the forward vehicle. Thus, the disclosed subject matter can provide vehicle headlight systems, which can emit favorable light patterns toward a pedestrian as a marking light, and which can provide favorable light distribution patterns to drive at night.

A control device for a vehicle lamp controls an adjustment of an optical axis angle of a vehicle lamp provided with a vibration generating source that vibrates at a first frequency, and the control device includes an acceleration sensor provided in the vehicle lamp and configured to sample an acceleration at a second frequency that is a non-integral multiple of the first frequency, a receiving unit that receives a signal indicating an output value from the acceleration sensor, and a controlling unit that executes control of adjusting the optical axis angle of the vehicle lamp on the basis of the output value from the acceleration sensor.
