Thanks, G-Benz. The rear left side-marker lamp is not functioning. The one that wraps around from the main left tail light and prevents someone from crashing broad-side into the car. I'll check those rails.

The turn signal saga continues. Yesterday evening while driving the right side turn signal started to malfunction like the left turn signal (i.e. blinking 5X faster than normal). Must be a coincidence relative to the side-marker light problem (I guess when it rains, it pours). Sounds like the turn signal combo relay that also controls the hazard light is the problem.
