I got the idea for this thread from this post (https://www.aaroads.com/forum/index.php?topic=12788.msg316029#msg316029) and this post (https://www.aaroads.com/forum/index.php?topic=12788.msg316081#msg316081) in the Traffic signals hanging by cables? thread.
Are there any traffic lights in you area that have the old paint starting to show? If so, post them here.
To start it off, here's a couple from Huntsville, AL. These are used as indicators to left train crews know that the crossing signals are operating.
This one has had most of the black paint come off and the yellow paint show through. Most of the yellow paint has since faded though.

These signals have fared better. However, some of the yellow paint is starting to show around the latches and visor tabs, but it is the most noticeable on one of the visors:

Originally yellow. Painted black in 1991, but much of the yellow is showing again.
Most of the black lights in Petersburg, VA have their original yellow showing through.
Originally took this photo for the signs, but the signals can be noted too. Original yellow signals painted black at the intersection of Bridge and Maple (US 4) Streets in White River Junction, VT.
