Abstract: A warning system for burned-out condition of automotive lamps including brake lamps, high-mount lamps and tail lamps, includes a detection circuit for monitoring the lamps to produce a first signal indicative of the presence of a burned-out lamp, and for monitoring a brake-lamp switch and a light switch to produce a second signal when the brake-lamp switch is ON and a third signal when the light switch is ON. The warning system also includes a control unit which receives the first, second and third signals and determines the identity of the lamp group including at least one burned-out lamp, and an indicator which indicates the identity of the lamp group including at least one burned-out lamp on the basis of the determination by the control unit.

Abstract: An auxiliary signal light for use in conjunction with the original equipment signal lights of a vehicle is disclosed including a light panel received within a container shaped base and covered by a translucent, nontransparent cover. The light panel includes a multiplicity of individual light units slidably received in apertures formed in a square, flat plate. Each of the individual light units include a base and a reflector lens which encapsulate a lamp and in the preferred form are factory sealed and replaceable as a unit. The light units are arranged around the perimeter of the square flat plate and along a horizontal diagonal between two corners of the square, flat plate. Thus, the perimeter light units form first and second generally horizontal V-shaped arrowheads pointing in opposite directions. By the utilization of diodes in the electrical interconnection, the diagonal light units are activated when either or both of the arrowheads are activated to form the arrow shank.

Abstract: An apparatus for measuring the mass of a flowing medium, in particular for measuring the aspirated air mass of an internal combustion engine. The apparatus has a hot wire disposed in the flow of the medium, the temperature of which is regulated in accordance with the mass of the medium; and its resistance is regulated by an adjustment variable which is a standard for the mass of the medium. The hot wire is guided on a sensor ring, which is of plastic, via support points. The support points are each fastened with a fastening section in a fastening slit of the sensor ring extending in the axial direction, and they each have a guide section protruding into the interior of the sensor ring through a radial slit. A guide wire extending in the flow direction is fastened to each guide section. The terminal support points in like manner, have attachment sections by way of which an electrical connection is made with the hot wire.
