I recall reading somewhere--seriously I believe the subject was raised on an N-Scale forum--that Federal regulations require markings on overhead obstructions up to 18'; the inference of this is that there are occasional vehicles reaching to that height. With that in mind I would draw the conclusion that traffric lights at intersections would be suspended at least 18' off the pavement which boils down to 2.5" in Horribly Oversized-Scale.

Thanks for your comments - I was thinking about 2 1/4 to 2 1/2, but I wasn't sure.
Thanks again.
At least 2" (14.5 scale feet exactly), I would use 2.25" (about 16 scale feet) on mine. Keep in mind trucks have heights up to 13'6" (or more, in some states), and the signals need to clear them.

Can anyone tell me what the proper approximate height in inches for HO scale for a traffic signal suspended over an interesection? Thanks for your help.
