I needed a streetlamp for a model I'm working on - I remembered cptnAWESOME's street sign, and thought I could make some quick adjustments to get a streetlamp that would suit my purposes.

Print Cap and Lens from this Thing. Assemble all parts with acetone or glue. I trimmed one of the copies of Pole_3 down by 15mm, adjust the height as you see fit. There is an open shaft through the center of all the street pole pieces - a kabob skewer fit perfectly and helped stabilize the pieces as I joined them together.
This is suitable for 1:24 models, with some room for additional scaling depending on the size needed. Shown with a 3" figure.
Love 3D printing and geography!
