Continuity mistake: Even after KITT's voice modulator changes to the three bars in the episode "Hearts of Stone," any shot of KITT starting himself up still shows the old voice modulator (a simple red square).
Continuity mistake: In the first few episodes watch KITT's glowing square. In some scenes the flasher says KNIGHT 2000 and other times it does not.
Chosen answer: Before "product placement" became common, name-brand products were rarely, if ever seen in TV shows, mostly due to avoid advertising conflicts with program sponsors. The Pepsi logo may have been taped out to prevent any commercial infringements.

Are you kidding? Product placement was so rampant in the 50s that sometimes you'd wonder if you were watching a TV show or a paid ad.

Knight Rider wasn't produced in the 1950s. TV shows of that era had advertising more similar to the old radio shows from the 30s and 40s. The early 50s series often had a sole sponsor, so their product (and related items) was likely seen in a program. An announcer also informed the audience at the beginning that, "This program is brought to you by (insert brand name). " From the 60s on, brand-name products weren't generally seen in TV programs. Networks sold air time to multiple advertisers, and their ads were shown during the long commercial breaks. So no, I'm not kidding.
