what did the street lamps seem like in a fog

towns and big cities across America are replacing overhead streetlight bulbs with brighter, longer-lasting versions. Embraced by communities mostly as a money-saving measure, the move can also deliver added quality-of-life benefits, in some cases even deterring crime by illuminating areas of town that were once poorly lit.
However, the American Medical Association is seeing the switch in a whole different light, even raising some health concerns that it's calling potentially "harmful." But to us, those concerns seem baffling and somewhat overblown, because when the AMA's policy statement is examined it's hard to discern what its concern is all about.
Before we get into that, let's first look up and see what's going on above our heads. In this nationwide street-scene overhaul, softer, high-pressure sodium lights are being phased out in favor of brighter, light-emitting diode (LED) lamps.
LED lighting, which has fallen in price enough to make it an affordable upgrade, burns more efficiently and lasts far longer than conventional street bulbs. They can function for 15 to 20 years -- in some cases four times longer than older bulbs -- and that durability also reduces the need for manual servicing. They also consume a lot less electricity. Small towns are "saving more than $57,000 annually on energy costs," while annual savings in big cities like New York can total $14 million -- "$6 million on energy costs and $8 million on maintenance."
