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 in phase with an energy output device that has a fixed duty cycle.

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

3. An oncoming headlight glare reduction device as defined in claim 1 that has an energy sensor device that that receives information from oncoming vehicle that allows co-ordination/synchronization of the phase of the said energy output device with respect to the oncoming vehicle.

4. An oncoming headlight glare reduction device as defined in claim 1 that has an energy transmission device that transmits information from vehicle that allows co-ordination/synchronization of the phase of the said energy output device with respect to the oncoming vehicle.

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

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