Answer 2

The searchlights have both white and IR LED lamps. Do not look directly into the searchlight in NVG mode as it may be hazardous to personnel. Also, avoid touching the searchlight in IR mode as it generates a lot of heat.

Use caution while using the white searchlight with NVGs. under some conditions the white light may impair visibility to the point of creating a hazard.
