Carnival of Spies

During filming of the episode in 1977, the show become associated with a strange American legend. Filming a scene in the funhouse called Laff-in-the-Dark a technician tried to move a strange looking wax-covered mannequin hanging from a rope and when he did the mummy's arm broke off in his hand. Sticking out of the wax was a human bone. When forensic scientists unclothed the figure they cut through the thick, hard wax and found that it was the body of Elmer McCurdy, a notorious outlaw who had been killed in a gunfight in 1911. After he was formally identified, he was buried in a formal ceremony and many of the crew of "The Six Million Dollar Man" were in attendance.

Most cars with horizontally-arranged dual-lamp headlights have the high beams toward the center and the low beams on the outside, and depending on how they're wired, either the high beams go on without the low beams, or all four lamps come on at the same time. So since the villains' car that Steve was tailing had just its high-beam (center) lamps on, it then would not have all four of its headlights on sometime later.
