Purple Streetlights

Have you noticed the rise of purple streetlights in your town? I haven't, but that may be because my small town is trying to look quaint and vintage to draw tourists. Purple streetlights are being noticed all across America. There must be a reason for that, but it turns out to be a pretty dumb reason. To get to the bottom of it, this video goes through the change from sodium vapor lamps on our streets to LEDs. Sure, there are a lot of advantages to LEDs, particularly in the amount of energy they use. They are certainly brighter, even though a lot of folks don't like them. The purple has been showing up only in the last few years, and it's not intentional.
