Methods, systems, and apparatus for lamp moisture management systems include a lamp housing including an inlet vent and an exit vent, a transparent cover plate covering a light exit hole in the lamp housing, and a conduit including a primary air inlet, an air outlet, a narrowed portion disposed between the primary air inlet and the air outlet, and a secondary air inlet disposed at the narrowed portion. The primary air inlet can be configured to receive a first flow of air through the conduit to induce a second flow of air through the lamp housing to evacuate a moist air from the lamp housing. Methods, systems, and apparatus can further include a fan configured to induce a flow of air through the lamp housing to evacuate a moist air therefrom.

Force air moisture management for lamps

Systems, methods, and other embodiments described herein relate to vehicle headlight calibration. In one embodiment, a headlight adjustment system includes a headlight positioned in a vehicle with a measuring assembly attached to the headlight. An adjust system is connected to the moving assembly and a moving mechanism. In response to an optical beam of the measuring assembly extending past an articulating reference member of the measuring assembly to an optical receptor of the measuring assembly, the moving mechanism physically alters a configuration of the headlight.

A method of autonomously controlling interior lighting of an occupied vehicle is provided. The method includes receiving vehicle-to-vehicle information from a nearby vehicle. A controller controls an illumination setting of an interior light of the occupied vehicle based on the vehicle-to-vehicle information.

Autonomous cabin lighting systems for vehicles

A vehicular lighting system includes low beam headlamps, high beam headlamps and a control unit configured so that during operation of the lighting system, the control unit determines the operational status of the high beam headlamp and selectively adjusts the illuminating intensity of the low beam headlamp. In particular, the brightness of the low beam headlamp can be increased during periods where the high beam is not being, thereby allowing the low beam to more closely approximate the brightness of the high beam, but without the glare associated with conventional high beam patterns. In this way, artificially low illuminating intensity limitations placed on the low beam headlamps can be overcome during periods where the lighting system is operating but the high beams are not in use. In one preferred configuration, at least the low beam headlamps are made from numerous individual light-emitting diodes that can be separately controlled in order to achieve the adjustments in low beam headlamp illuminating intensity.

Low beam intensity control unit

A light with improved moisture control for a vehicle. The light has a housing and a lens, the housing and the lens forming a light interior. The light also includes a lamp that is at least partially enclosed within the light interior. A vent duct is included and extends through the housing from the light interior to an exterior of the light. An anti-humidity fan is present within the vent duct and is operable to move moisture from the light interior to the exterior of the light and thereby prevent fogging of the light lens.
