Devonte I believe there are a many originals but some are replacements, in fact they still are installed in new instillations today BTW I almost got one of these
Liability issues, that utility was concerned if I got injured from the lights that my parents might sue, a little extreem to say the least (that would NEVER happen) but for that reason they wouldn't give me any lights
I wonder if any other utility uses these lights or where to even get them.
