What is the height requirement range for stop lamps/tail lamps?

The correct height requirement range for stop lamps and tail lamps is indeed from 15 inches to 72 inches above the ground. This range is established to ensure that the lights are visible to other drivers on the road, which is crucial for safety. Tail lamps should be positioned so they can effectively communicate the vehicle's presence and actions to others, particularly in conditions of low visibility or at night.

Positioning the lights within this height range addresses visibility factors such as the size of the vehicle and the natural line of sight for drivers in other vehicles. If the tail lamps are placed lower than 15 inches, they might not be easily seen by other motorists, which could lead to accidents. Conversely, if they are above 72 inches, they may be too high for effective visibility to standard passenger vehicles.

The other height ranges provided do not align with the established safety standards for stop lamps and tail lamps, which is why the chosen height range is the most appropriate.
