GREEN BAY, Wis. (AP) — Some Wisconsin communities that have installed high efficiency traffic lights are discovering the energy-saving bulbs are a hazard in a snow storm.
City officials say the LED lights use less electricity and don't give off enough heat to melt ice or snow. So when the snow falls and the wind blows, the traffic lights are obscured.

This stinks... LED lights, to me anyway, are much easier to see at night.
Making life better by making it worse.
This shouldn’t be a problem since battery powered cars probably won’t run in freezing weather anyways ;-)
Grandma was killed in a traffic accident!!! *sniff* Well, as long as the city has saved thousands in power bills... I guess it was a worthy cause./s
I thought civil engineers thought of things like this. Yeah, they'll save electricity, but how much are you paying all those work crews? And if they are on overtime, forget it!
Oh what a tangled web we weave,,,, i love these kind of consequences,,
Libs are dumber than dirt.
Surely if they have solar cells to make electricity, they have snowlar ones too?
I know the traffic engineer where I live. The city installed LED lights about a year ago, and he predicted the same thing would happen with his. The city planners were so entralled about the energy savings that they completely overlooked the traffic hazard they present in the winter time.
Union members too?
“I thought civil engineers thought of things like this”
Yeah,, You’d think a VERY basic test on a new traffic signal would be how behaves in hot, cold, wet, and arid,,, night, and day. But i mean,, im no engineer,,,,lol.
we have a whacked liberal City Councilman in Pittsburgh who wants to convert all of our street lights to LED...
Only draws power in very cold weather
Do I have to think of everything?
Testing is much less rigid if one merely slaps a “green” label on something.
Heck, I would be surprised if this idea was tested at all!
“The city planners were so entralled about the energy savings”
Which they will promptly lose as soon as they get clobbered for their first lawsuit where someone is killed, because the red light design couldnt be seen for being covered in snow.
You got that right about the “green” label.
All negated in one or 2 days of crews cleaning off the lights.
Especially the left and right turn lights that have a smaller surface area lit.
Why is this an issue? The traffic regs say if the light is out, including if it cannot be understood, then you treat the light as a red light and stop. Anyone blowing through a controlled intersection is an idiot.
No problem! They’ll just install heaters so the total energy use = 125% of the old way.
Exactly the situation near me this morning. About 50% of the traffic blew through the off signal as though it was bright green.
Reminds me of that time in the 70s that Chicago bought a whole bunch of new, improved road salt that would melt snow down to 0 degrees F.
Only problem was that it gets to zero a lot in Chicago, then what was melted before would refreeze into a real slick sheet of ice and couldn't be melted.
(except that the number with most likely be north of 125%)
When I was in Vietnam years ago, we kept a lit 60W light bulb in the bottom of our barracks lockers so that our clothing and other stuff didn’t get moldy. It isn’t just for cold weather that we NEED incandescent lights.
“Anyone blowing through a controlled intersection is an idiot.”
True, that. Unfortunately, our roads are filled with idiots who barely have any clue about the rules of the road. They have no idea that flashing red equals “stop”, or that no signal equals “stop.”
For what it’s worth, I love my LED flashlights. Very bright, and they use so little power, you can use “dead” batteries in them (batteries that can no longer run other devices).
Of course, icing up doesn’t apply to them.
You git that right. I've almost been killed by people plowing into the back of me and people blowing through the intersection when the lights were out. Morons...
BTW, is your screen name a reference to the Rush song?
And you can bake cupcakes with a 60w light. You also can keep newborn little animals warm with one a couple feet overhead.
Here in Colorado we went from a “No Fault” to an “At Fault” insurance program. hehe. People started seeing their insurance skyrocket as they had accidents and it was their fault. “Gosh, officer, I thought I could turn right from the far left lane.”
I can also see them easier when the sun is shining on them, as well. Much easier to see than the old bulbs.
Wait a minute! We have those new energy-efficient mercury-filled-curly-cued-lightbulbs- just the thing to do the trick to heat up the LED`s!
They could have left the red incandescent bulbs in place and still had cost savings on electricity.
Once the jackasses have blinders on, it’s hard to get them off.
I realize not all traffic from all directions will be affected as the blowing snow/ice generally will only cover part of the light, but can't these lights be centrally controled and turned to flashing red if it appears something is wrong for at least one direction of traffic? Also, as was mentioned in a previous post, what about a simple thermal switch and heating coil to kick on when temps drop below a certain level?
According to Al Gore, this shouldn’t have been a problem because “global warming” should have precluded the chance of it ever snowing again. All the polar bears should have been dead by now and all the icebergs should have melted.
I agree. However, most lemmings out there only do what the light tells them. If they can see the light, they may not be aware that the others facing them, or cross-traffic, cannot.
Why not set an emergency procedure that in inclement weather of this nature, all lights flash red and all intersections are to be treated as four-way stops.
They did think about it! More union jobs...every city now needs to hire additional union members to clear the snow out of the traffic lights.
Stupid, unenlightened, mouth breathing, joe-six pack, Walmart shoppers are soooo stupid! (Crash!)
(upside down dead superior progressive that got hit at the snow covered light)
LOL.... my gawd! Do I have to tell those northerners how to do everything... :-)
Just put a little heater on it, and only have it switch on during precipitation and freezing weather...
I mean, could it be simpler? They won’t have a whole lot of days of the year where they’ll even have to have it on... :-)
The big advantage to LEDs is not so much the power but that they take less maintenance (changing bulbs). The problem with the ice could easily be solved with a thermostatically controlled heater.
Like fire hydrants, traffic lights need to be designed to function in any weather (hydrants in areas that freeze automatically drain when closed.)
The lens heater is a good idea to melt snow. While the incandescents melt the snow anyway, in much of the country, like my part of Texas, that function is necessary maybe eight hours a year. The lower energy consumption is a BIG DEAL on things like traffic lights that are supposed to function 24/7/365.
Just as most people will insist that GREEN means GO NO MATTER WHAT.
“BTW, is your screen name a reference to the Rush song?”
Yes, and also to the fact that I live relatively near to Toronto now.
Sounds like a "shovel-ready project" to me. More jobs saved or created on TOTUS' watch.
Cool. I am a huge Rush fan (saw them probably 5 times in the 80’s) and love that song. The drum solo from Exit Stage Left is a classic. Also a big fan of Neal Peart’s books.
Very good.....like the way you think Joe !
