For tha majority of my life I lived in Northern Ohio, where the idea of back-lit street blades at signalized intersections were (and still) pretty much non-existent. It wasn't until I moved out west when I saw back-lit blades hanging at intersections as more of a norm in urban areas.
Within the last 2-3 years, my locality replaced all of the bqck-lit (flourescent and LED) blades and replaced them with hi-res reflective metal blades. I assume that this was to save energy, not have to replaced burnt-out signs, and to have slightly larger signs at many of the intersections.
I was kinda bummed to see these go, some not even 5 years old.
Has your area been phasing out back-lit street-name signs, or just upgrading them to LED lightingassemblies? I'm curious to see if this is an increasing trend.
