Porch light .. Dusk to Dawn not working

The glass/plastic that covers the light sensor on the front of an outdoor light can become so dirty that the sensor can't distinguish light from dark. If you unscrew that disc and gently clean it (no harsh chemicals!), you stand a strong chance that the light will again work as it should. If it doesn't, it's possible the sensor has gone bad although that isn't likely. Good luck!
