The first episode, ‘Knight of the Phoenix’, KITT was a little different than most people remember.
The first half of the show saw him with a modified ‘stock’ nose which, to my knowledge, no-one has reproduced yet as most people don’t find it as appealing as the nose Michael Scheffe designed for the second half, and subsequent three seasons.
The dash was also more of a cover than a replacement dashboard. It finished just in front of the stock speaker locations and was attached to the stock dash pad.
The Voicebox, where you saw KITT speak was a pulsating single light through a diffused lens.
The front nosecone had plexiglass covers over the turn signals.
