The American Plate
The upper jaw of a cartilaginous fish is not attached like it is in bony fish, although both sets of jaws work in the same way. Bony fish have a protective bony plate that covers the gills. Cartilaginous fish lack this covering but have their own way of protecting the gills.

There are plastic bulb covers on either side of the license plate. Unscrew the screws and take the covers off. From there you can insert new bulbs.
As a GENERAL rule plate covers are legal as long as they do not change the colors of the license plate or obscure the letters/numbers or state of issue in any way.(note: due to the discoloring action of the sun on plastics, some so-called 'clear' plastics tend to turn yellow pretty quickly - once that occurs they are no longer 'clear.')
