A heads-up display for moving vehicles such as an airplane or automobile and which includes a transparent sheet which may be the windscreen or windshield of the vehicle. An extremely thin enhancing film is secured in intimate contact with the transparent sheet and disposed within the sheet, if it is a laminated sheet such as a safety glass sheet or on that side of the sheet which is on the interior of the vehicle, or which may be made integral with the composition which makes up the transparent sheet. The enhancing film is an absorber or blocker of selected lightwaves which match the lightwaves of a display of indicia projected against the interior side of the windscreen. The assembly of film in sheet eliminates the need for a separate, independent indicia reflector to replace between the windscreen and the operator of the vehicle.
