A rearview mirror assembly for vehicles which displays information useful to the driver/viewer when viewing the mirror assembly. Indicia are formed by narrow deletion lines, preferably using computer controlled laser marking apparatus, in a reflective coating on a mirror element of the assembly. A light source, which may be a light emitting diode, an incandescent bulb or another type source, is positioned behind the mirror element to illuminate the indicia for distinct, clear, precise visibility by the driver/viewer. The lines of the deletion area are sufficiently narrow as to be generally unnoticeable to the unaided viewer's eyes when a rear vision image is reflected by the reflecting surface and the light source is unlit thereby preventing interference with normal driving use of the mirror assembly. The light source may be used to simultaneously illuminate portions of the vehicle as well as the deletion area indicia.
