PURPOSE: A facility surveying reflector for collimating at night is provided to emit light to a prism by an LED lamp, thereby easily collimating even in a dark place or at night by changing a position of the reflector. CONSTITUTION: A facility surveying reflector for collimating at night comprises a supporting stand(110), a reflector(120), a light(130), and a power source unit(140). The supporting stand is formed into a rectangular shape and fixed on the ground. The reflector is comprised in the upper part of the supporting stand, thereby transmitting light being emitted from an LED lamp(131) from a surveying device for collimating. The light comprises the LED lamp being comprised in a rear surface of the reflector, thereby emitting light to the reflector. The power source unit is connected to the light, thereby supplying power.
