Abstract: A solid state flasher for plural turn signal and emergency warning lamps for trucks or the like, capable of flashing very heavy loads with small voltage drop without contact arching and pitting, including a cylindrical cup-shaped housing can, a dielectric disc-shaped closure wafer closing and sealing the open end of the can, an input terminal/heatsink member in the form of a cylindrical tubular metallic shell axially spanning the can having a contact prong projecting through a slot in the closure wafer, an output terminal member of generally rectangular shape adjacent and paralleling the wafer and including a contact prong extending through another wafer slot, and a circuit board assembly having a solid state flasher circuit thereon supported inwardly parallel to the output terminal member.

Abstract: A combined center high mounted stop lamp and cargo lamp assembly for pick-up trucks, vans and the like, including a unitary integral molded laterally elongated casing member to be mounted on a truck cab, van, or the like, shaped to provide an exterior hood-like collar formation defining an encircling surround about a horizontal transverse elongated plural lamp zone for three side-by-side lamps. Three truncated substantially parabolic reflector cellular formations extend from the collar formation toward the front of the vehicle in use position defining lamb-bulb-housing reflector cavities directing light rearwardly of the vehicle and being provided with reflective metal coatings on the inner surfaces thereof. A red lens is supported by said collar formation in rearwardly covering relation to the centermost cellular formation and white lenses are provided for the other two cellular formations.

Abstract: A heavy duty lamp flasher for turn signals for trucks, trailers and the like including a switching relay having normally open and normally closed contacts and a moveable relay arm and relay coil, and an arc suppression circuit formed of a transistor or pair of transistors connected in parallel with the switching relay to minimize contact arcing and load carrying limitations. A diode and capacitor pair is connected to an integrated circuit oscillator for activating and deactivating the relay and another diode and capacitor pair is connected to the gate of the transistor and to the relay coil, such that the mechanical contacts of the relay, with their inherent mechanical delay, control the transistor circuitry so that the transistor provides the primary current path during movement of the arm between the normally closed and normally open contacts and the normally open contact provides the primary current path when it is closed.

Abstract: A modular multi-function lamp assembly of plural shock mount lamps for automotive vehicles, such as trucks, trailers and the like, made up of interchangeable lamp modules, including a generally cup-shaped assembly housing having walls defining an outwardly opening cavity for receiving a plurality of individual lamp modules in a vertical stacked array aligned with each other and nested within the cavity. Each module includes a case having sides and a lens, a lamp bulb and shock mount therein, with at least one side forming a flat planiform abutment wall to be disposed in confronting abutment with a paired companion like abutment wall of an adjacent module. The abutment walls have interlocking formation to restrain them in assembled relationship, and the modules have protruding rib formations along opposite sides to be received in recessed channels in sides of the housing for holding the modules in the housing.

Abstract: A shock absorbing mount for a vehicle lamp bulb including an integral flexible plastic suspension member for supporting the bulb in spaced relation to a reflector with the bulb axis arranged horizontally. The suspension device has a central receptacle formation for receiving and supporting an end portion of the bulb horizontally, three flexible arms integrally joining the receptacle formation at equal circumferentially spaced locations each extending radially outwardly from a cylindrical surface of the receptacle at their roots and continuing outwardly as a serpentine recurved strip curving about a pair of horizontal axes of curvature along like vertical reverse curved paths for accommodating displacement of the central receptacle formation in all directions.

Abstract: A three module turn signal switch assembly for heavy trucks and the like comprising an actuating lever housing module, an electric switch module, and a plug module in the form of separately produced units assembled together and removable from each other. The actuating lever module comprises a module casing, a handle member forming a control lever, a yoke member pivotally supporting the handle for lateral and vertical movement, and detent structure to define handle positions for Left Turn, Off, Right Turn and Emergency switch conditions. The switch module is releasably connected to the lever housing module and includes a casing and rotatable armature member driven responsive movement of the handle to these positions, and includes fixed contacts and movable actuator conductor segments to provide proper current paths for the selective switching functions.

Abstract: .Iadd.A lamp assembly particularly suited for vehicle mounting and adapted to be subjected to vibratory shock loads including a rigid reflector and a relatively flexible bulb suspension structure supported on the reflector having a receptacle or basket formation for receiving a bulb. The suspension structure includes a pair of elastically deformable flexible arms extending laterally oppositely from the receptacle formation along horizontal serpentine paths having portions forming U-curves about vertical axes to accommodate horizontal flexing and are pivotally mounted at their outer ends on the reflector..Iaddend.
