Especially in the first season, but also in many scenes in seasons 2 and 3, KITT had so-called “Grillbars” in the openings for the fog lights in the front bumper - strips to protect the fog lights. These grillbars can be optionally ordered for all KITT front bumpers (except for season 4), depending on which “look” of KITT you want to build or which one you like best.

For the front bumper of season 4, there are no grillbars, as KITT never had grillbars in season 4 and the fog lights were mounted further forward. In addition, the openings in the front are slightly larger and slightly curved at the top, as seen in the series. The straight grillbars would not fit visually into the overall picture here.
