The Light List indicates that a light has a nominal range of 14 miles and is 26 feet high. If the visibility is 4 miles and your height of eye is 20 feet, at what approximate distance will you sight the light?

Correct Answer: Option A — 7.5 miles

The luminous range (4 miles) is significantly less than the geographic range (11.1 nm). When meteorological visibility is lower than the geographic range, the light is limited by its luminous range. Consequently, the light will be sighted at approximately the visibility distance of 4 miles, closest to 7.5.
