20080316012 | Goods-Carrying Vehicle with Lighting Units that can be Controlled by Means of Plc (Power Line Communication) - The invention relates to a utility vehicle, in particular a truck with or without a trailer, having an on-board electric power system ( | 12-25-2008 |
20100085179 | VEHICLE LIGHT SYSTEM - One embodiment of the present application includes a vehicle illumination system. The vehicle illumination system comprises an input keypad configured to receive at least one input provided by a user. The vehicle illumination system also comprises a controller configured to receive input commands provided by the input keypad and to sequentially control a state of a plurality of output device drivers corresponding to a respective plurality of vehicle lamps. The vehicle illumination system also comprises mean for reducing or eliminating undesired LED illumination. The vehicle illumination system further comprises overvoltage protection circuitry configured to continuously monitor an electrical signal associated with each of the plurality of output device drivers relative to respective over-current condition thresholds and a summation over-current condition threshold. The summation over-current threshold can be less than a sum of the respective over-current condition thresholds associated with each of the plurality of outputs. | 04-08-2010 |
20100295670 | INTERIOR INFORMATION DISPLAY APPARATUS AND LIGHT IRRADIATION APPARATUS USED FOR THE SAME - Information is displayed by irradiating a visible light on a specific position based on at least one of vehicle state information, vehicle surrounding information, and vehicle interior information. For example, the visible light is irradiated on a target switch based on signals indicating an on/off state of a headlamp operation switch and an on/off state of a key switch. A user | 11-25-2010 |

20130321142 | VEHICLE HEADLIGHT STATE MONITORING METHODS, SYSTEMS AND PROCESSOR-READABLE MEDIA - A video-based vehicle headlight state monitoring method and system. A vehicle image can be captured by an image-capturing unit and converted to a grayscale image. The grayscale image can be processed to locate a front license plate and identify a position of a headlight region in front of the vehicle utilizing an algorithm. An average digital count with respect to brightness of the headlight region can be compared with average digital count with respect to brightness of several parts of the vehicle and a background region to determine the vehicle headlights ON/OFF status. The headlights can be considered ON if the digital count level of the headlight region is higher than the digital count of the several parts of the vehicle and the background region. A warning signal can be initiated to turn the headlights on during a special situation utilizing a signal generator. | 12-05-2013 |
20140167951 | VEHICLE FUSE AND BRAKE LIGHT MONITOR - The present invention relates to a device in a motor vehicle having a system for monitoring the active status of vehicle light bulbs such as brake light bulbs and the corresponding light fuse and reporting the status to a vehicle driver. | 06-19-2014 |
20140313027 | HEADLIGHT STATUS DISPLAY SYSTEM FOR AUTOMOBILE - A headlight status display system for automobile that includes a plurality of spare bulbs wired in a secondary relay circuit, each of said plurality of spare bulbs disposed proximal each of a plurality of primary bulbs wired in a first relay circuit, wherein failure of any one of said plurality of primary bulbs is detectable and communicable to a driver and, simultaneously, a corresponding one of the plurality of spare bulbs is illuminable in lieu of said failed primary bulb, whereby an automobile's visibilty is ensured and proper functioning of either headlight or rear light is maintained. | 10-23-2014 |
