Fixed lights are usually mounted so they can be:

• A. Raised, lowered, and turned.
• B. Removed for remote use.
• C. Used to signal helicopters.
• D. Used to bypass Ground Fault Interrupter.

Answer: (A)

The main idea is that fixed lights are mounted in a way that lets you position illumination exactly where it’s needed by changing height and direction. Raising the light increases the distance of light coverage and helps reach higher or wider areas, while lowering it brings the beam closer for detail work or to work around obstacles. Turning the light lets you aim the beam around corners or shifts in the scene, so you can illuminate different zones without moving the fixture.

The other options aren’t typical uses: fixed lights aren’t intended to be removed for remote use, they aren’t used as signaling devices for helicopters, and bypassing a Ground Fault Interrupter is unsafe and not how these lights are operated.
