So is there any way of knowing how long they were used over the later years Bill? I was wondering if they'd be the same for as long as the 7 inch round seal beam bulbs were used, 1977 I believe..
And thanks for that info

Round 12V seal beam (non halogen) for single headlamps used thru 1979 on Thunderbird, thru 1980 C series Tilt Cabs.
1979 F100/350's sold as fleet vehicles also have round headlamps. There were also single round headlamps used on misc 1980's BIG trucks, but these use a halogen bulb.
Since there's no 1956 part number, there's nothing to compare it to.
