You might be thinking of sodium vapor lights

  Yes! Why doesn't everyone just use these? Where there's astronomical concerns or people agree its just a nice and worthwhile end to be able to see the night sky, maybe use the low-pressure sodium but yeah. Edit: I wonder what gets used in "rich" places in contrast to "poor" places. I feel like rich people get the night sky and poor people get headaches and insomnia. So sick of this shit
