Abstract: An improved insulating material is provided. The insulating material is a mixture of an insulating fluid and solid insulative bodies. The insulating material exhibits desirable insulating, conformal coating, surface adhesion, and low-viscosity characteristics. For example, when the insulating material is used to fill the cavity of a hollow insulator, the insulating material prevents any moisture that enters the insulator from adhering to the walls that define the cavity; thus maintaining the insulating qualities of the insulator. In the event that some of the fluid is lost through leakage, the insulating material also aids in preserving the insulating qualities of the insulator.

Abstract: A vehicle lighting system includes a door lock light and switch module removably supported on a door edge and including a light emitting diode to illuminate the door lock and circuit means to energize a courtesy light in the vehicle and wherein associated circuit means including a door operated switch maintain the courtesy light illuminated once the door is unlocked and delay circuit means for maintaining the overhead light energized following door closure with transistorized cutoff means being included to terminate overhead illumination when the ignition switch of the vehicle is turned on.
