Sirens Perched on Traffic Signals Scream Blackout Warning

Item

Air-raid sirens in Los Angeles, Calif., will sound their warning blasts from atop traffic signals where a convenient perch has been found for them. The stop-and-go lights, too, have been made ready for blackout. Each light is provided with a metal cover having a narrow slit through which motorists can see the light, but the beam is not brilliant enough for enemy observers to see it.
