A gravity actuated switch and an automotive under hood or under deck lid light assembly utilizing the switch. The switch includes a blade and a ball mounted for rolling movement along the blade in response to a change in attitude of the switch. The ball is operative in response to such rolling movement to move the blade between a first configuration in which the switch is open and a second configuration in which the switch is closed. The blade comprises a beam member formed of a spring material arranged in cantilever fashion. The spring material of the beam is electrically conductive and the beam forms a part of the electrical circuit path through the switch.

A mounting structure and methodology for mounting audio speakers in the package shelf of a motor vehicle. The speakers are mounted in a well formed integrally with the package shelf. The well opens at its upper end in the package shelf and defines an annular ledge at its lower end sized to seat the annular flange of the speaker. Resilient spring fingers on the annular wall of the well flex outwardly in response to insertion of the speaker into the well to allow passage of the speaker flange and thereafter, upon seating of the speaker flange on the ledge, flex inwardly to lockingly clamp the speaker flange between the spring fingers and the ledge. A grille structure includes a grille sized to fill the opening in the package shelf and a plurality of fingers extending downwardly from the grille and sized to fit within the well structure. The grille structure is installed with the grille fingers extending downwardly into the well for interlocking engagement with locking tab portions on the spring fingers and for engagement at their lower ends with the upper face of the speaker flange. The grille further includes a plurality of locking fingers which coact with holes in the panel so that, as the fingers of the grille structure interlock with the spring fingers and assume a position in clamping relation to the upper face of the speaker flange, the locking fingers snap into the holes in the panel to lock the grille structure to the panel.

A circuit for use in providing high voltage power to a neon bulb positioned on the vehicle utilizing the vehicle DC battery as the power source. The circuit includes an invertor, a transformer, and a rectifier. The invertor receives low voltage DC from the vehicle battery, converts the low voltage DC to a low voltage AC drive voltage, and delivers the AC drive voltage to the transformer primary for conversion to a high voltage AC at the transformer secondary. The rectifier receives the high voltage AC from the transformer secondary, converts the high voltage AC to high voltage DC, and delivers the high voltage DC to the neon bulb. Since the power delivered to the neon tube is DC there is less need to shield the tube with respect to electro magnetic emissions and parasitic losses in the wire runs between the battery and the neon tube are significantly reduced.
