'Light pollution' has reduced dramatically in the UK in the past 5 or 6 years too.
This is due to local councils and The Highways Agency moving from 'Sodium' bulbs (the orange ones) to new 'LED' type of bulbs which have almost all of their light directed downwards.
The sodium bulbs used to emit their orange light in a much greater arc, and also (IIRC) at a different, longer, wavelength to standard lightbulbs. They were originally chosen due to their light being better able to cover a larger area and be visible in less clear conditions, such as mist and rain/spray.
These modern LED lights I find are rather hopeless as they do not give off a sufficiently bright light, and also are less powerful anyway. The existing streetlights were originally installed the correct distance apart for the sodium bulbs used at the time, and as such we now have pools of unlit street between the lights.
But, 'short story', less light pollution now.
