We have these in-road LED fixtures in a few miles of our Interstate-70 in the mountains here in Colorado and I must say I love em.  Very very cool.  Glad we are expanding this.

That's a neat idea but likely be expensive to maintain. The road is a brutal place, they will get torn up. If they're  solar powered the batteries will need replacing after a few years. Give it 5 years and many probably won't be working... Unless your DOT there stays on top of things. I just see a bunch of marketing hoopla and $$$$$$$. I could be wrong

HUGE waste of money.

We put these in a few years ago, they didn't last 6 months (I work for a DOT) they did seem tough but the traffic is tougher.

I also saw these in Shanghai about 12 years ago, right after the highway was opened. Being China, the ENTIRE highway had its lane markers outlined in these LED lights. After a year, it seemed less than 2% were working. But they looked awesome on inaugural day!

we have some solar powered LED's at a daycare center around here... they've been working right since 2010 I think, however they're not the prettiest things to look at.

The ones they put in along I-70 a few years back are so far holding up quite well.. And that is with plow trucks and salt and salt brine solution and what not being thrown over it.

Yup, a private school near here put a bunch of solar powered streetlights in, they are ok but sure are ugly with the battery box on the top and off to the side.

Here are several solar LED lanterns at the Yarkon Park. One of them glowing dimly.

If it isinthemiddle of nowhere,it makes perfect sense to usethis type (the questionis,why to useanything at all, but I keep that out for now). The thing is, a local solar powered system, mainly where are 360 sunnydays per year, is way cheaper tha the power distribution infrastructure for classic grid fed lanterns...

They are not talking about solar garden lights, solar lanterns or solar theory.

These are in-road solar LED modules. They are exposed to the worst conditions possible, including semi trucks driving over them. They don't last and are a waste of public funds.

Na Semis aren't bad they just roll over the top of them, it's the snow plows they do the real damage with there blade down...

But they are a neat idea, and they are also using something like this for the mindless zombie smart phone using pedestrians Here

What on earth is wrong with the traditional 'cats eyes' they have been working fine since 1934. If it 'ain't broke don't fix it.

I like these lights... They should make them with EL plates... they'd take less energy than LED's.. i'd imagine it being a servicers nightmare but imagine if they make some sort of electroluminescent road paint.. so the lines would glow...

You certainly get paint with reflective beads suspended in it so that it glows when your headlights shine on it.

Glass beads in the paint are great and so are those Cat-eyes, but if you want to use modern technologies why not adopt Thermal Imaging in the car with a heads up display, It's not that new BMW, Cadillac where doing it over a decade ago...

Glass beads in paint and cats eyes are cheap and easy to maintain and FLIR in cars is great, but not everyone will have it.
