The heights of the streetlights and “parking lot” style lights are approximately 24 scale feet in height from the base to the lighting unit, which is a common standard for both primary and secondary road illumination. This is scaled for a typical single or double-lane road, and the road type can be suggested on your layout by simply altering the spacing of sequential poles or following local DOT requirements, if known. For parking lots, the single tube head tends to be used along the perimeter of the lot, and the double head between the rows of parking spaces.
