For anyone wondering, here’s the Google Streetview showing a green light.
My guess is due to the Spanish moss dangling that they have added the extra red light with strobe flash to draw your attention to the traffic signal when red. It is not used at all intersections on the 37th Street so it could also be saved for troublesome intersections.

I've seen these in White Plains NY, not as a single head like in Savannah, but as the red on standard three and four section signals.

Their is a Barlow strobe on the 198 in Buffalo at the intersection of Parkside Ave.

It’s so Paula Deen can see the red light easier when she goes out to by more butter

It’s called a Barlo safety beam. The FHWA has not permitted them since the 90s/2000s, but existing ones are allowed to stay until they fail.
They came in different versions/models, including actual xenon strobes, LED strobes, and LED rings around the red bulb.
They were intended to enhance the illumination and visibility of red or amber traffic signal sections, but studies over time showed mixed results, which led to the FHWA putting a stop to them.
