Generating sounds in a vehicle, including generating turn indicator/hazard warning lights (TI/HWL) sounds via a first channel, and generating additional sounds via a second channel, where the second channel is different than the first channel.

A warning device for a vehicle comprising a number plate support portion for supporting a number plate. The warning device further comprises a warning indicator. The number plate support portion is movably attached to the warning indicator. The number plate support portion is moveable from a first position covering the warning indicator to a second position revealing the warning indicator. Further, the warning device comprises a number plate support portion pivotably attached to the warning Indicator such that the number plate support portion and the warning device fold together and fold apart when the number plate support portion is moved between the first position and the second position.

An after-market, low cost and easily installed vehicular door safety warning light system using electromechanical actuation for automatically providing a visual warning to passing traffic that a car door is opening and passengers are about to exit the vehicle. The safety warning light system includes a magnetically actuated switch to effectuate the light-emitting elements, wherein the light-emitting elements are automatically switched on only when the car door is opened and are highly visible throughout the entire opening arc of the door and do not shut off until the vehicle door is closed. The light-emitting elements are uniquely housed as a single device in a single housing or a plurality of jointed sections adapted to fit and adhere to the variable contours and inner surface areas of and along an open car door regardless of the vehicle's make or model.

A vehicle includes an image sensor configured to acquire a surrounding image; a sensor configured to detect at least one of a vehicle state or a surrounding condition of the vehicle; an external display disposed on an outer side of the vehicle; and a controller configured to identify whether a predetermined situation occurs based on at least one of the acquired surrounding image or an output value of the sensor, and configured to control at least one of a flicker frequency or a flicker pattern of the external display to display information on the occurring situation when the predetermined situation occurs.

A self-assembling network is configured to automatically and dynamically connect devices used in operations carried out on or near roads bearing vehicle and pedestrian traffic. An automatic, ad hoc network connecting existing and new devices can be used to enhance safety by gathering and exchanging safety critical information. In some cases, existing equipment can be augmented with a network controller and radio frequency communications to permit the devices to join a wireless local network and exchange information over the network. New devices, including wearable devices, can be configured to act as nodes on the wireless local network. Establishing the relative position of vehicles, sensors, wearables, and other nodes on the disclosed ad hoc wireless network allows the coordination of functions based on position.

In connection with a ground transportation vehicle light head (86) powered by a battery-based voltage source (20) supplying positive (76) and reference (i.e., ground) (78) voltages that define a voltage difference (22) applied across a number of multiple series-connected high-power light-emitting diodes (HP LEDs) (12) and current regulator circuitry (80) electrically connected to them, ultra-low dropout circuit techniques are disclosed for increasing a portion of the voltage difference available from the battery-based voltage source to forward bias and thereby maximize the number of the multiple series-connected HP LEDs emitting light by maintaining a low voltage drop (82) across the current regulator circuitry. By maintaining the low voltage drop and making available from the battery-based voltage source an increased portion of the voltage difference, at least one additional HP LED is capable of being forward biased to thereby maximize the number of multiple series-connected HP LEDs emitting light from the light head.

A blind spot warning indication device for an exterior mirror of an automobile includes a light guide member. A plurality of wedge-shaped bosses are arranged side by side along an axis on the light guide member corresponding to a setting direction of the PCB. One side of each of the plurality of wedge-shaped bosses has a light incident end surface for aligning with a corresponding light source. An upper surface of each of the plurality of wedge-shaped bosses includes a light reflecting side having an optical pattern for reflecting and scattering. The reflecting side having the optical pattern is an upwardly convex arc surface. A lower surface of the wedge-shaped boss has a light emitting side. The outermost wedge-shaped boss has the largest curvature of the light-reflecting side compared to the other wedge-shaped bosses arranged side by side, and the outermost wedge-shaped boss has the longest length of the light-emitting side compared to the other wedge-shaped bosses arranged side by side. The device has the functions of reflection and scattering at the same time. The uniformity of the emitted light at the front surface and certain angles is better, and the warning effectiveness is improved. The LOGO pattern can be better combined with the emitted light.
