Hugh, that’s a very easy oversight to make because I believe the actual lights, the housing and lenses, were used in 67. So you are right there.
But not the sequential part in 67.
They added that for 68.
For the first Ford to have them, I found an article from Hagerty, the car people, that states thewere designed and planned for the 64 T-bird, but that their use was delayed one year to the 65 model because they were outlawed in certain States.
By 65 all States had passed legislation to make them legal, and the article states that’s when they went into use on production cars.
I’ll write my question tonight.
