I find that they do a much better job of lighting the street and the boulevards, sidewalks and make it easier to see pedestrians at intersections. The light from them is almost identical in color to the old Mercury Vapor lights that were all removed in the early nineties. Those pink/orange Sodium bulbs just created a lot of glare and made everything on the sidewalks look black. From a driver's point of view they were worse than having no streetlights at all. It was almost impossible to see pedestrians wearing dark clothing, unless they were right under the streetlight. It would have literally been better to drive with just headlights. The new LED streetlights are a vast improvement over the Sodium lights.
The LED's do look cold though, compared to the warm glow from the pink/orange lights, but I'd much rather have the far superior light output of the LED's.
