What is the distance between the left and right stem lights on a T light pattern?

• A. 14 meters
• B. 20 meters
• C. 7 meters
• D. 10 meters

Answer: (B)

Spacing in a T light pattern means how far apart the two outer lights are along the top bar of the T. In this arrangement, the left and right stem lights form the ends of that top bar, and the standard span between them is 20 meters. That places each light 10 meters from the center, giving a symmetrical crossbar that clearly defines the T shape from a distance. The other distances don’t match this documented top-bar length, so they wouldn’t produce the correct, recognizable pattern.
