Here is a kit I built for 200mm LED traffic lanterns based off of what information I could find available + dozens of reference photos I've taken over time.
They're similar to 2 different styles commonly found around Perth, Western Australia; Aldridge and Braums.
There are only 8 maps used in the model: LEDs x 6, Push Button Label, Controller Cabinet Faults info.
The remainder is made up of basic materials, simply containing colours based on their real world counterparts.
The light colour is a combination of self illumination and a fog colour on the lenses.
