So, I've had 2 other '54 trucks and a '52, but never noticed until today that there are 2 indicator lights in the speedo.
One, I know is the high beam. One I'm not sure about.
The one at the 12 o'clock position shines red when you put a light through it. The second, at the 6 o'clock position seems like it doesn't have a lense in it and just shows white.
I've also never had a truck with "factory" turn signals, the others always had the add-on Guide system. Is it possible that the 2nd light is for the turn signals? One light for both sides?
