4 Pack SnapPower GuideLight 2 LED Outlet Wall Plate - Automatic On/Off Sensor Night Light - New Version Light Almond Duplex - Perfect for Hallways, Bedrooms & Bathrooms at Night

These LED socket covers are great! Not too bright, but bright enough that you don't have to turn on over head lights....AND, you still have both outlets free instead of one being taken up by a bulky night light.My son loved this when he was younger. I prefer total darkness. He now does too. It's still on. When the lights die. I switch back the old panel or I'll sell the house.I have installed four of these innovative night lights in my house so far. I am very happy with how they work and how easy they are to install.One SnapPower Guidelight is in the front hallway on a regular decora wall plug. It was very easy to install. Three more SnapPower Guidelight devices are installed on regular decra wall plugs that are on GFCI "protected" circuits in a bathroom over a sink and in the kitchen over the countertops. GFCI stands for ground-fault circuit interrupter.Now this is important: If those outlets had been actual GFCI outlets, then the SnapPower device would not have lit up their three LED lights. That is because GFCI plugs are built differently than regular outlets. GFCI plugs do not have electrically charged screws located on their sides in the same place that regular outlets have theirs located. So the SnapPower device will not fit right on a GFCI outlet to receive electricity to power the LED lights. Take that into account when you are deciding where you want to put them and how many to buy, and then you should be fine.I did have a problem installing the device on one outlet. After repeatedly inserting and removing the device, I finally took an actual look at the outlet installed inside the wall box. I found the problem. This outlet had black electrical tape wrapped around the terminals on its sides. That prevented the SnapPower Guidelight from making proper contact with the outlets' electric power terminals. I cut back the tape from the terminals on both sides, and then it worked just like the other ones I installed.As for why there was the electrical tape on some outlets and not on other outlets, the answer is that some electricians are more cautious. They do this to prevent potential problems later on. They use the belt AND suspenders technique to prevent electrical shorts from happening inside the wall box.You do need to know this next fact when you decide where to install these lights. The LED lights will be shining down if the outlet was installed with its ground hole on the bottom side of each socket. The LED lights will be shining up if the outlet was installed upside down, with its ground hole on the top side of each socket. This is important to know because there may be places you want it shining downward where you do not want it to shine upward, and vice versa.My only complaint about this device is that the photo sensor is not sensitive enough to the ambient light in the room. It often does not cut off the LED light in the daytime. It lights up when there is adequate natural light to see with, but the LED lights do turn off when there is slightly brighter daylight. This condition means the device uses a couple extra pennies a year of electricity because it is lit in the daytime when it is not needed. However, they claim that it now uses about ten cents a year in electricity, so fixing that problem is not very significant.They should fix the sensor eventually, but it is so good now that they may not get around to doing that anytime soon.Works amazing in the hallJamaisIt did meet my expectations and as claimed was just a simple replacement.Works great!great product, fast delivery..
