Does anyone have any info of this searchlight replacement?
PL-1-01 programmable laser projector with a pulse function. Being a laser projector rather than a regular xenon lamp, the PL-1-01 can illuminate targets much further away due to less scattering of light over distance and because the laser is projected in a much narrower beam than the IR light from a lamp, so according to the inverse-square law, the area illuminated is smaller but the light is much more intense. The pulse function improves light penetration into dense fog or haze by reducing backscatter. PL-1-01 is used on the BTR-82A and on the modernized BMP-2 and can be used as a laser rangefinder. It may be used in the same way on the modernized T-80 as well, assuming that the night sight has been replaced. No word on what the replacement sight is, though.
