Only started noticing this today. In every city I’ve ever lived in (east and west coast US), pedestrian walk signals have this triangular pattern grate over the actual lights that show the walk or wait imagery. Considering the panels use lights that are made to those actual shapes and not a pixelated display, what’s the purpose of the grate?

I had to look it up because I couldn’t imagine what you’re seeing. My state doesn’t use these but I would lean towards some sort of protection against vandalism or just protecting them from getting damaged or obstructed.
