At night, drones will look like little dots of light (either red or green) moving across the sky. Some drones will emit a blinking white/green/red light visible for several miles, and you may mistake them for stars.

What color lights do drones have at night?

The major thing that differentiates police drones from other drones is their strobe light. Police strobe lights have blue and red colors. If you are a few meters away from a police drone at night, one side of the drone will have a red light and the other side will have a blue light.

How do you tell if a drone is spying on you?

Radio. If you think you are being spied on, the best way of confirming this is by using radio counter-surveillance systems to track down the drone. A radio counter-surveillance system decodes radio waves generated by the drone and makes a pattern to show where the signals are coming from.
