As a point of curiosity, have you investigated the wiring harness near the bumper for wear? On one similar project, this made a big difference. While reading through various setups of different vehicle lighting, I came across Bnlboston Limo and took notice of how professional cars deal with visibility and placement of lights, which did give me some ideas on improving my setup.

Last post here was 18 years ago, but your insights seem very plausible.
Of Note; The later 2 versions of the '72 lights are a capsule ( clear and Amber)
and the symptoms on those are usually in the harness socket which has its own ground. Early models seem to have what you describe.
IIRC the changes occurred in Nov, and Dec of 1971. Lets see your car pics Mr Smith ! Welcome to The Py Forums!
