I would like to thank all of you for the help and suggestions,
This is a donated car to the Automobile Museum, and we do find that a lot of them with incorrect bulbs have been installed.(and a lot of other things, we just found a well rusted lug nut in the head of a 1929 Chrysler)
I did test at the socket with the brake petale pushed down, and power came through around 6 volts.
The tail light lights up when the lights are turned on.
Looking at it I do not think the pins are aligned (matched) on the socket and bulb, that is what got me thinking that it could be the incorrect bulb.. (I will look at the 1158 and 1154 Bulbs)
Thank you for the help and suggestions.
