Claim 0:
1. A method for light adaptation of the eyes of a driver of a vehicle when exiting a tunnel, wherein the method comprises:
determining a tunnel exit position, and
changing a light source luminous flux of at least one light source in the vehicle as the vehicle approaches the tunnel exit position in response to the determination of the tunnel exit position;
upon determining the tunnel exit position:
determining a tunnel exit time for the vehicle to reach the tunnel exit position, and
determining a light adaptation time,
if the tunnel exit time is equal to or shorter than the light adaptation time,
changing the light source luminous flux of the at least one light source in the vehicle as the vehicle approaches the tunnel exit position during the tunnel exit time, and
wherein the at least one light source is configured to emit light of various colors and/or emit light of various color temperatures, the method further comprises:
determining at least one of a color or a color temperature of light at the tunnel exit position,
matching a color and/or a color temperature of light emitted by the at least one light source in the vehicle to the determined at least one of color or color temperature of light at the tunnel exit position.
