Several European countries have a white or yellow reflective border around traffic lights to help with recognition, especially for those who might be color-blind: with a bright rectangle, it's easier to see the position of which light is lit, rather that only rely on the color. A couple decades later, I'm now noticing some traffic lights in the US starting to gain this feature. I'm sure it will help with machines trying to parse the traffic light state... and also humans.
