Are helicopter searchlights fixed or movable? Can the helicopter crew move the helicopter searchlights or are they always fixed at a specific location on the helicopter?

They are used by rescue helicopters mostly but I am not sure if crew can move them to look at specific area by some method or they are always fixed.
The question is some what unclear, but helicopters usually have some combination of 3 types of lights.

Landing light(s); fixed, sometimes pulsing, used for illuminating the area directly in front of and below the helicopter for landing.

Anti-collision light; fixed red and green and a strobe on the tail and sometimes the belly.

Search lights; directable, usually only used on military or para-public helicopters that fly at night. [SAR, Police, etc...]
