Nowadays it is, but there were times in which enamel was the only permanent material to be used on road signs, and that doesn't reflect at all.

Surely now there is no other sense to use them than decoration.

Here's another example of such signs in Belgium:



Further on in the distance you can see the same information, but on a reflective sign. I'm not sure whether the lights still work in this one though.

This is what it looks like at the other side:



As far as I'm aware, these old signs are still being maintained, but there aren't any new ones being placed any more. This internal lighting system is also used on some destination signs, but I haven't got any pictures of those yet. I'll see if I can get to that intersection tomorrow.

As promised, I took pictures of those other signs as well today.

During my trip I realised that I was wrong about those signs not being placed any more. A couple of years ago, some new ones were placed at the intersection I was thinking about...

Anyway, I do think those internally illuminated signs can be handy if you want to place a sign higher than a car's light can illuminate. Example:



This is one of those new signs that I remembered, also notice that the traffic signs to the left are internally illuminated. The bottom one is in dire need for replacement though...



I hadn't noticed this before, while I had already driven past here hundreds of times: this sign has the same information on both sides, making the light work for two sides at the same time. At this spot however, I don't really feel that a sign has to be placed so high and thus the need for illumination isn't there. Either way, I liked discovering it.



Other side, same sign:



A bit further on there's an intersection where this type of sign is also used. I'm not sure why they decided to do that, but there's no point changing anything there now because they'll change the whole intersection in about 2 years anyway. Still, I felt it was worth taking pictures of:





And then I realised that a bit further on, there was an illuminated sign which I always thought was odd and realised I should just go take a picture of it as well to share it with you guys. Taking a picture of it while illuminated was hard though because the sign is actually flashing all the time. The reason for this is that this bridge consists of two bridges next to each other, one for each direction, and sometimes people who come from the lane on the left of the picture think that they can also just turn left (despite what the signs clearly say). It's probably therefore that they tried to make it overly clear that the bridge shouldn't be entered from that side. The sign isn't lit internally, but it is padded with LEDs in the corresponding colour of that part of the sign.

There are several here in Athens, Georgia. Unfortunately, I don't have pictures.

Illuminated signs allow drivers to be able to read them much sooner than reflective signs. Reflective signs only do any good once car lights are close enough to reflect off them, which sometimes can be a very short window if you're traveling along at a pretty decent clip.

It seems to me that lit signs are a waste of resources. Just use reflective paint, or if it's absolutely needed just put a light in front of it or on top of it.

I agree, but it's nice to have a few unique curiosities like that around.

Well, in Belgium pretty much every sign that's on a motorway and isn't placed where a car's lights would shine has internal lighting.

Perhaps this is done because the motorway itself is also illuminated for a big part of the night? Perhaps that has an effect on the readability of those signs or so.

I read somewhere that out of energy/money conservation, they don't illuminate highways at night after 10pm, unless there is fog or rain. Is that true?

Only smaller signs in the US are lit up like that - larger ones are standard reflective metal, with lights shining on it from underneath. (It also seems to me that internally-lit signs are always mounted above the roadway, not on the side)

Hmm, I'm not sure, but I'd estimate that time to be more like 11:30pm, and even then the entries, exits and interchanges are still illuminated - because those are illuminated all night.

It seems like they are common in the Phillipines as well.

South Africa has quite a few of them. They are always sponsored by a fast food outlet or something like that, which has its own sign on top.

Here's an old photo of Voortrekker Road, the signs are now white but otherwise the same. Credit Etiennedup on Flickr image hosted on flickr

The City of Maple Ridge BC has them I know, on the signs identifying the street name. But only where there are traffic lights. I THINK there are a few in the city of Port Coquitlam to the west as well.

Keep in mind that alot of people have night blindness issues which visually impares them at night so having these signs would be helpful in certain scenarios. There were a few times when I was driving in a different city myself that I was unable to read any street signs because it was so dark out and the sign was in an area which the headlights did not reflect any light.

Well it's not blatantly obvious if you are at the intersection as the signal does not have a red arrow.
