A vehicle may have lights such as headlights and other vehicle lights for providing vehicle illumination. The lights may be electrically adjustable so that the color and pattern of the illumination may be varied. Sensor data and/or other data may be used in determining how to adjust the lights. A light such as headlight may have a light source such as a white light source or multicolored light source, a light collimator that receives light from the light source, and an adjustable lens array that receives collimated light from the light collimator and outputs corresponding adjustable vehicle illumination. The adjustable lens array may have fixed and/or adjustable lens elements and corresponding electrically adjustable light modulator elements.
