This might reveal our age if we can remember when?

It occurred to me this morning it was still dark outside. I Was driving to spend the day with my elderly mother, and I had to keep using bright lights to dim lights as I was driving down at two-lane Road through the country and all of a sudden I remember using the dim and bright lights on the floorboard brought back memories of my 73 Pontiac Lemans. Was just wondering what others might remember from days past that younger ones might know.
