These robots are god damn clowns. Hershel snuck over to the lights, too determined to feel utterly ridiculous like he normally would. He reached the lights just as the other robot started poking the disembodied head in the eye because apparently they had nothing better to do.

Hershel stepped behind the lights, waiting a moment before flashing one of the lights right in the robot's faces, making them both drop the poor head and start jerking a bit. Apparently their sensors really didn't like the lights, but they were quickly adapting, and he tried flashing the light on and off a bit to slow that down.
