Some prior studies concerned with visibility, legibility and effects upon crashes of various types of license plates were reviewed. License plate manufacturing processes were reviewed and outlined. Samples of license plates were constructed. Photometric measurements of the reflectivity of these plates and a sample of automobile reflex reflectors were made before and after exposure to the SAE J575e Corrosion Test. The effects on reflectivity of the corrosion testing were generally minor, except for license plates made with the beaded legend, which also showed a moderate degree of rust in the legend. No changes in color of the legend or background were noticeable.
