brake lights need key on to work

I would think sometime before 1957 because my truck is the same .

Unless you are talking about tail lights ? Then the newer ones would be controlled through a delay module and the fob

This new to me, I have never known a vehicle to need key on for brake lights.

I talked to the service rep today and GM did that for many years to prevent brake switches which stick from draining the battery. I checked out some new cars and they work when key is off.
