Abstract

When a vehicle, such as a school bus, is operating during non-daylight conditions and/or in foggy weather with its headlights on, and the vehicle stops to pick up or discharge students, headlight glare, from the school bus, may impair some portion of an on coming driver's field of view of a stopped bus making the bus and the children not clearly visible, if visible at all. This is especially true if the headlights would be a little out of adjustment and as the bus is a truck with higher headlights than a car and the position of the stopped bus has a bearing on where it's headlights are pointed when it is stopped. This invention operates the headlights at a reduced intensity during the non-daylight hours of operation and at full intensity during the daylight hours when the school bus is stopped and the red flashers are operating and the headlights are in the alternating flashing mode during picking up or discharging students. There will be a headlight module to reduce the intensity of the lights. This module will be activated by a signal from the red flashers system (ie. door switch, ground speed sensor, flasher activation system, headlight alternating flashing system) and controlled with a light sensor so the intensity of the headlights is only reduced during the non-daylight hours. This will work with the continuous on headlights and will work especially well with the headlights in the alternating flashing mode.

DESCRIPTION OF THE INVENTION

1          What is the problem or issue (if any) that your invention is meant to solve?

When a vehicle, such as a school bus, is operating during non-daylight conditions and/or in foggy weather with its headlights on, and the vehicle stops to pick up or discharge students, headlight glare, from the school bus, may impair some portion of an on coming driver’s field of view of a stopped bus making the bus and the children not clearly visible, if visible at all.   This is especially true if the headlights would be a little out of adjustment and as the bus is a truck with higher headlights than a car and the position of the stopped bus has a bearing on where it’s headlights are pointed when it is stopped._______________________________________________________________________________________________

2          How was the problem or issue handled (addressed/solved) before your invention? Attach sketches, drawings, photos, and/or reports where possible to answer this question.

Nothing is being done to reduce the intensity of the lights, but headlights are now alternating on & off to draw attention to the school bus but even this is not reducing the glair and providing increased visibility of the school bus._____________________________________________

The system would not change the intensity of the headlights until the red flashers are operating and the flashers do not come on until the door is opened to pick up or discharge st...
