Photocell Sensor for Outdoor Post Light, Dusk to Dawn Sensor, 120V Photoelectric Switch for Pole Light, Lamp Post Light Sensor, Waterproof, UL Listed

Pay attention to how it wires. Does work just fine.

It was easy to replace my existing one that wasn’t working anymore what is good about it you can use the existing plug by cutting it off the faulty one and wire to this one with either the supplied wire nuts or wire splicers which I did. Everything else is just easy and the unit works well.

Perfect and thankful that Amazon has this item as our local hardware store and big box stores no longer stock this item

This looked like an almost exact copy of my original dusk to dawn sensor that went bad. It wired in just like the old one. It's diameter is a fraction of a millimeter larger than the original sensor, though. It took me about 3 minutes with a grinding attachment on my drill to widen the opening enough to get it in. It comes with a rubber seal that my original sensor didn't have. I didn't notice it in the box, but when my son pointed it out to me, it was easy to put on by simply loosening the screws on the sensor, working it out a little, and stretching the seal in place before tightening the screws again.

There is a timer built into these sensors to prevent flashing on/off when cars go by at night. So when you install one, wait a minute for it to cycle when testing.Fits well and works well.

It warked

Worked like a champ for 3 months, then quit working. Poor quality, for 3 months of usage, not really economical.

Nice eye for the new post. The only suggestion I have is that the included screws be self tapping.
