Abstract: A method and system for controlling exterior lights on a vehicle. The method includes receiving an input indicative of a desired mode of operation of the exterior lights from a user-selectable input device. The user-selectable input device includes an on-setting, an off-setting, and an automatic-setting. The method further includes receiving sensor data indicative of a level of visibility outside the vehicle, comparing the sensor data to a threshold, and generating, by an electronic processor, a notification indicative of an improper positioning of the user-selectable input device when the sensor data indicates that the level of visibility is less than the threshold and the user-selectable input device is positioned in the off-setting.

Abstract: A hydraulic accumulator assembly for a hydraulic brake system. The accumulator assembly includes a pump housing having therein at least one accumulator bore. The accumulator bore has an axis and an inner wall. A piston is movable within the accumulator bore and divides the accumulator bore into an accumulator chamber, which is communicable with the hydraulic brake system, and a spring chamber. There is a spring in the spring chamber for biasing the piston in the direction of the accumulator chamber. A passageway in the pump housing is closely spaced from the inner wall so as to form a relatively thin wall thickness between the passageway and the inner wall. A vent bore is punched in the inner wall and communicates between the spring chamber and the passageway. The vent bore is punched in a direction away from the axis.

Abstract: A rotor rides on the shaft end and is eccentric with respect to the rotational axis of the shaft. The rotor rotates in the bore of a pivot ring and coacts therewith in the nature of a double action pumping such that there are two pumping cycles per revolution of the shaft.
