How many cities do you know have internally illuminated street signs?

Internaly illumated street signs are basicaly street signs that light up at night in order to assist drivers with visibility. They are usually lit up using LED lights or Fluorescent Bulbs.

Two examples of internaly illuminated street signs along with a link to an article that goes into more detail.

These are relatively common in parts of the U.S. especialy in the states of California, Colorado (mostly in the Denver area), Nevada, Arizona, Texas, Illinois (mostly around Chicago), Michigan, and Florida from my experience and from looking at certain photos.

An example in the Galleria area Houston, TX

Any other cities that have these?

There are some in Miami-Dade County, Florida (USA), not just street signs but traffic control signs as well.

Unnecessary if you have reflective signs (unless they're posted on a place car-lights don't illuminate).

In the 60's, most overhead signage in the Netherlands was lit from below, but they have replaced them with regular diamond grade reflective signs. That saves considerably in maintenance and cost. If the lights were broken for whatever reason, you simply can't read the sign.

Belgium still uses internally lit signage extensively, although there has been some progression towards reflective signage recently.

I've never seen anything like this any place I've been in the US. Do they still have them in France?

I doubt if France ever used internally lit signs on Autoroutes. they probably did use them in cities.

The old-style French signage looks like this;

Here's a Belgian internally lit sign. You can recognize them because they are much thicker than regular signs. It may be 15 - 20 centimeters thick to provide space for the internal lighting structure.

Also note the vandalism, this is Belgium after all.

Yep, in French cities. Including Caen, where I studied for a summer, too long ago. There are examples (some from Caen) in this thread:

"Lüttich"! In German-speaking Belgium (where French is accommodated as a second language). That might be linguistic vandalism, although I didn't think - [warning - generalization!] - that was much of an issue between German- and French-speaking Belgians

There are a handful of internally-lit signs in the Virginia side of the greater Washington area, but they're not common. (Using a fluorescent backlight) On wide highways, signs posted on overhead gantries use lights shining on it from underneath, and if it's reasonable to assume cars' headlights will be effective at the proper angle, every other sign is reflective. (I think every road sign except internally-lit ones are reflective anyway)

When I was in Orlando there were alot of them around. Maybe they are just concentrated in the more tourist heavy areas?

We have them in my city on newer traffic light gantries. They're mostly for decorative purposes.

Does the MUTCD specify specifications for fluorescent street signs?

Isn't that a waste of money and electricity? (the internally lit signs, not the traffic lights) I mean, aren't reflective signs sufficient?
