" I do wonder how a ground issue could result in the high beam indicator being on, albeit too dimly to see it during the day."

It glows because the indicator lamp is providing a poor ground path .

Like the millions of old 50's & 60' GM products that have a dim taillight that goes out when you step on the brake : the secondary filament provides a ground path until you energize that circuit then the light goes out .

Auto electrics isn't rocket science, you just need to learn it by doing, you'll get this fixed ere long .
