Various toy versions of KITT have been released. Among the best-known Knight Rider memorabilia is the remote controlled KITT, the Knight Rider lunch box, and the deluxe version of KITT. The deluxe model of KITT, sold by Kenner Toys and dubbed the "Knight 2000 Voice Car", spoke electronically (actual voice of William Daniels), featured a detailed interior and a Michael Knight action figure. ERTL released die-cast toys of KITT in three different sizes—the common miniature sized model, a 'medium' sized model, and a large sized model.

In December 2012, Diamond Select Toys released a talking electronic 1/15 scale KITT which features a light up dashboard, scanner, foglights and tail lights along with the original voice of KITT, William Daniels, all at a push of a button. Mattel has released two die-cast metal models of KARR.

The small one however lacks the amber scanner light and instead retains the red scanner from KARR's appearance in Trust Doesn't Rust and there is also a KITT which is completely identical to KARR in its first episode in Trust Doesn't Rust. KITT and KARR are both in Knight Rider: The Game and its sequel. They also appear in the Knight Rider World in Lego Dimensions.
