New to the poll making. Sorry if this doesn't work well.
SELECT ONE CHOICE FROM EACH CATEGORY.
Select 1 of the 3 'size' options
Select 1 of the 4 'lenses' options
Select 1 of the 2 'preference' options
You should have made 3 votes, one in each category, which is labeled in parenthesise at the beginning of each option.
(This will make the percentages off. Just look at the numbers in the results.)
Answer based on what is on your area currently.
Around me there are mostly 12" signals and a few 16". There are no 9".
All of both types are LED with countdowns, except for 1 single 12" incandescent symbol pair. (Until around 2010 I think, they were all worded incandescent signals of both 9" and 12", with a few with symbols. There were no 16" signals then.)
The 12" signals are from an (oddly?) large variety of brands, including McCain, Siemens, Mark IV (Eagle), Eagle Durasig, TCT, CH, Peek, Fortran, Econolite, and more. All 16" signals are Siemens.
I'm lucky to live in a not-very-major place with pedestrian signals at almost every intersection in town. I much prefer the 12" signals, because I think they look better, and I think the functionality of the multiple sections is more useful.
