Fixed. The problem was in my reconnecting the wiring to the faulty side, I matched “what went where” to the the locations on the other side, but things were reversed on that other side. The tip-off was that on the two sides, different filaments were lit in their respective bulbs when the running lights were on, with one too bright and the other too dim. I switched the leads going to the faulty side’s bulb socket as well as to the spades at rear of housing. Voila! Happy New Year! 💥
