Are there different names for the different types of street light styles, such as these in NYC: http://goo.gl/maps/mh8zo and this: http://goo.gl/maps/9Q1Di
Would this one be a universal style, with the one spoke in the arm of the light: http://goo.gl/maps/z2Yux with many variations.
What would be the best street light style you have seen?
