Abstract: A method for controlling the intensity of light within an interior passenger compartment in a motor vehicle to create perceived sensations of safety, comfort and personal accommodation in conjunction with specified, night time, driving-related occurrences. The natural human desire for safety is satisfied as a driver approaches a parked motor vehicle by illuminating the interior passenger compartment with a plurality of light sources (18, 20, 22) in response to having produced a safety approach signal. The natural human desire to be comfortable within a confined space is satisfied by the act of opening the door (28), whereupon the interior illumination intensity is automatically lowered to a second intensity level. Once the transmission shift selector is moved out of its Park condition, the interior light intensity is automatically decreased to a third intensity level to provide the sensation of stress reduction and thus satisfy the natural human desire to be at peace.

Abstract: An incandescent automotive lamp for mounting in a lamp socket comprising a light-transmitting envelope, an insulating base, and a plurality of conductive wires. The light-transmitting envelope contains an energizable light source and has a sealed-end portion. The insulating base includes a housing, a flange portion, a plurality of channels, and a divider portion. The housing has a cavity in which the sealed-end portion is secured. The flange portion is located on the housing and has a substantially bevelled frustum and a rim with diametrically opposed notches. Each channel passes through the housing and leads into the cavity. The divider portion depends from the bottom of the housing. The divider portion has a pair of substantially flat faces, a pair of sides, and a bottom. At least one of the faces is adjacent to the channels of the housing. Each side has a base notch. The conductive wires connect to the energizable light source and pass through the sealed-end portion of the envelope.
