Mostly, I'm interested to know when Ford added an actual brake light. The electric tail light came out in 1919 for the starter cars (right...?) and I believe it was just a running light for when the headlights were on. Of course, the non-starter cars stuck with kerosene tail lamps.
What years were the various styles of tail lamps used? Did the 26/27 Ts have a brake light, or were they still using just running lights?
Thank you for your responses!
From Erik's link it looks like a brake light became an option in March of 26.
Stop lamps on autos were an early '20's thing, some more expensive cars had them, the lowly Ford not among that group. Ford finally succumbed to accessory fads, and offered the Ford combo Stop and Tail lamp for the Improved Car.
The '27 American Rolls Royce had tail light, brake light and back-up light! However,only on one side! Fancy German Silver three-lamp set and license plate holder.
