Claim:
1. An electronic device for a window of a vehicle, comprising: first and second glass substrates laminated to one another via a first laminating material forming a vehicle window, the first and second substrates having substantially matching curvatures and being adapted for installation in the vehicle at an angle that is not normal to a first intended viewer's line of sight; a sheet supporting a first set of LEDs; and a first holographic optical element configured to be interposed between the first set of LEDs and a first intended viewer of the first set of LEDs, wherein the first set of LEDs and the first optical element are laminated between a cover glass substrate and the first substrate with a second laminating material, wherein the first glass substrate is located between the second glass substrate and the cover glass substrates, and wherein the cover glass substrate is smaller in size than are the first and second glass substrates; and wherein the first holographic optical element includes a plurality of optical elements, the optical elements being configured to redirect light output from the LEDs in at least two different directions, so that light emitted from the first set of LEDs is substantially directed in a direction away from a front-to-rear axis of the vehicle, but is redirected by the first holographic optical element so as to be directed substantially parallel to the front-to-rear axis of the vehicle and toward another driver; wherein the cover glass substrate is thinner than each of the first and second glass substrates; and wherein the first holographic element is located directly between (a) a laminating material that laminates the first holographic element to the cover glass substrate, and (b) the laminating sheet supporting the first set of LEDs.
