Captain speaking: Yehudi lights are lamps installed on aircraft in order to make its average brightness the same as the brightness of the sky, making it harder to spot.

It was developed by the USA in 1943 and they stopped using it due to the widespread use of radar targeting systems and the fact that the Yehudi light equipment is quite cumbersome and fragile.

Yehudi lights are ineffective against satellite detection though since they can't hide its shilouette against the landscape below. And the martians have very good sensor on their landing castles as seen when castle saazbaum could find Slaine's Sky Carrier as soon as they reached orbit above Japan. In comparison, the satellites we have would most likely need hours if not days to accomplish the same task.
