I bought some fancy-shmancy dusk-to-dawn light bulbs with motion sensors a month or two ago for the fixture outside my front door, but they just weren't working. I was trying to save some electricity by not having them lit all the time, but guess what--coming in and out of the door literally a foot away from the sensor and not having it light up was a serious pain in the tush. Plus, I'm a single female living alone, and I do everything I can to increase my security. Having these bulbs always on when it's dark out is worth it to me. It's always lit up when I come and go at night, which makes dealing with keys and steps and grocery bags and whatever else so much easier and safer. And it turns off during the day when it's not needed without me having to do a thing. No timers, no constantly remembering to flip the switch or cursing because I forgot to turn the light on/off. Easy.
