People who fix the lights at the top of airplane radio towers usually have to climb them in the middle of the night. If a light burns out on the tower, late- night hours are the most cost-effective time for a station to power down, which protects the climbers from exposure to dangerous radio frequencies as they ascend upwards of 200 feet in the dark.
