There are a few people street lights near me in Seattle and now I probably know why. I thought it was a vain (!) attempt to deter intravenous drug use.
I did gather that's why some bathrooms have blue lights, but yeah, it wouldn't make much sense to have random street lights have that.
Drug policy ramble, it's proven more beneficial to offer clean, well-lit places to shoot drugs, along with mental & medical health personnel and free methadon.
