Abstract

An oncoming headlight glare reduction system using a controlled shuttering of a shield and the strobing of the headlight.

Claims

1. An oncoming headlight glare reduction device for vehicles that has a means of generating a control signal to control an energy shield and energy output device.

2. An energy shield defined in 1 that changes state via said control signal.

3. An energy output device defined in 1 that changes state via said control signal.

4. An energy shield defined in 2 that changes state via said control signal.

5. An energy output device defined in 3 that changes state via said control signal.

6. An oncoming headlight glare reduction device as defined in 1 that has an energy sensor device that that receives information from oncoming vehicle that allows co-ordination/synchronization of said energy output device.

7. An oncoming headlight glare reduction device as defined in 1 that has an energy transmission device that transmits information from vehicle that allows co-ordination/synchronization of said energy output device.

8. An oncoming headlight glare reduction device as in 1 that has an input from Magnetic readings.

9. An oncoming headlight glare reduction device as in 1 that has an input from Global Positioning Systems.
