A light had flashed in the room upon the second floor.
The red light on the top of the car was flashing.
The green light of the sun was flashing in my eyes.
But I could see there was a red light flashing on the board.
Let's go and see if that light is flashing tonight.
Almost immediately, a single blue light flashed three times on the water.
A red light flashed on the surface of the door.
Some distance to the right, and higher up than they were, a light was flashing.
Lights flashed between my eyes and the rest of the world.
