A vehicle collision warning system includes a first sensor that generates a first signal indicating a traffic condition. The system includes an external warning signal system that emits an external warning signal to warn nearby traffic about a hazard condition. The external warning signal system includes a warning device configured to emit the external warning signal, and a processor. The processor receives the first signal from the first sensor, detects the hazard condition based on the first signal, and generates a control signal to cause the warning device to emit the external warning signal.

A visual deceleration indication apparatus signals to pedestrians and other vehicles that a vehicle is slowing down or coming to a stop. Illuminating devices, such as LEDs, contained in a license plate frame located in the front of the car, are activated when the vehicle decelerates. An accelerometer or other sensory device is used to detect deceleration and sends a signal to illuminate the LEDs, thereby letting others know that the vehicle is slowing down. The license plate frame may be connected directly to a rear brake light component without the use of accelerometers or other sensors. When the brake is applied, the LEDs in the license plate frame are illuminated. The LEDs may be contained in other forms and located in different positions on the front or side of the car.

A light assembly for a vehicle. The light assembly includes a housing having a front side and a rear side, wherein the rear side is removably securable to a vehicle. The front side of the housing includes a perimeter light, a center light, and a platform light, wherein the lights can alert vehicles approaching a stopping vehicle. The perimeter light is disposed around a perimeter of the housing and can produce an amber color. The center light includes an indicia in a non-colored transparent material and the platform light, disposed between the perimeter light and the center light, that produces a red color. In one embodiment, the light assembly is operably connected to remote control, allowing a user to activate and deactivate the light assembly.

A communication system for a vehicle comprises a mechanism for sensing a braking of the vehicle and a control device for sending a signal to a headlight activation circuit to modulate the vehicle's headlights based upon the braking of the vehicle. In particular, a headlight of the vehicle is able to be modulated based upon an application of one or both of a front brake and a rear brake. The headlight activation circuit is able to modulate the headlight between an on position and an off position or modulate the headlight between a high beam position and a low beam position. Consequently, the vehicle is better seen as it approaches likely congestion areas such as intersections and slowing or stopped traffic and attempts to enter traffic.

A communication system for a vehicle comprises a mechanism for sensing a change in speed of the vehicle and a control device for sending a signal to a headlight activation circuit to modulate the vehicle's headlights based upon the change in speed. In particular, a headlight of the vehicle is able to be modulated as the vehicle reduces speed and/or is decelerating as it approaches an intersection. Additionally, the headlight of the vehicle is able to be modulated as the vehicle accelerates from a stopped position or reaches a certain traveling speed. The headlight activation circuit is able to modulate the headlight between an on position and an off position or modulate the headlight between a high beam position and a low beam position. Consequently, the vehicle is better seen as it approaches likely congestion areas such as intersections and slowing or stopped traffic and attempts to enter traffic.

An apparatus may comprise a base member being defined by a rectangular aperture configured to receive and engage an automobile intake box, the base member being further defined by a perimeter surrounding the rectangular aperture and having at least one fastener or aperture configured to receive a fastener dimensioned to avoid disturbing the automobile intake box; a gooseneck member fixedly attached to the base member, the gooseneck member having a first end opening and a second end opening, the gooseneck member having an interior cavity configured to direct air into the automobile intake box from the second end opening to the first end opening through the interior cavity; and an interchangeable bell housing removably secured to the second end opening of the gooseneck member, the interchangeable bell housing having a frustoconical shaped cross section on at least one plane.

A light assembly for a school bus. The light assembly includes a housing having a front side and a rear side, wherein the rear side is mountable to a school bus. The front side of the housing includes a perimeter light, a stop light, and a platform light, wherein the lights can alert vehicles approaching a stopping school bus. The perimeter light is disposed around a perimeter of the housing and can produce an amber color. The stop light includes the word stop in a non-colored transparent material and the platform light, disposed between the perimeter light and the stop light, can produce a red color. In one embodiment, the light assembly is operably connected to a control, speedometer, and door assembly of a school bus, allowing the light assembly to automatically activate when the school bus stops and automatically deactivate when the school bus door closes.

Systems, apparatus and methods implemented in algorithms, software, firmware, logic, or circuitry may be configured to process data and sensory input to determine whether an object external to an autonomous vehicle (e.g., another vehicle, a pedestrian, a bicyclist, etc.) may be a potential collision threat to the autonomous vehicle. The autonomous vehicle may include a light emitter positioned external to a surface of the autonomous vehicle and being configured to implement a visual alert by emitting light from the light emitter. Data representing a light pattern may be received by the light emitter and the light emitted by the display may be indicative of the light pattern. The light pattern may be selected to gain the attention of the object (e.g., a pedestrian, a driver of a car, a bicyclists, etc.) in order to avoid the potential collision or to alert the object to the presence of the autonomous vehicle.

[OBJECT] To clearly awaken a pedestrian who crosses in front of an automobile to the fact that an automobile driver is depressing a brake pedal.

[ACHIEVING MEANS] The invention is a display device of operation state of automobile brake that includes a brake operation detection switch (Bp) and a light emitting device (2). The brake operation detection switch (Bp) is actuated by depressing a brake pedal (3) and outputs a brake actuating signal to the light emitting device (2). The light emitting device (2) is disposed on an undersurface of a front of an automobile body (1), and emits diffused light in a fixed range of the front of the automobile body by receiving an input of the brake actuating signal so that the diffused light forms an optical projection image (Pi) on a road within a range of a shadow of the automobile body (1) as a caution arousing sign. Apedestrian looks at the opticalprojection image (Pi) displayed in the shadow (1a) of the automobile body (1), and ascertains that a brake operation is being performed, thus enabling the pedestrian to cross a pedestrian crossing at ease.
