The electronic displays can have 640.times.480 or greater resolution. Some roof-mounted embodiments have three electronic displays arranged in a triangle, with two displays each visible from the front and one side of the vehicle, and the third display visible from the behind the vehicle. Some roof-mounted embodiments include an enclosure for their display(s) and drive circuitry; one or more roof protectors having a weight distributing surface shaped to fit the curved roof of a vehicle on which they are mounted; and a plurality of mountings supported by the one or more roof protectors for suspending the enclosure in a position spaced above the roof, which mounting includes vibration isolators, for at least partially isolating the enclosure from vibration of the vehicle roof.
