To install house number lights, select a good location, figure out a stress-free power source, and use lots and lots of meticulous measurement strategies. First, you’ll want to choose a place for your number lights that’s easy to see from the street, and also easy to drill in for installation purposes. Place your number lights there in the desired configuration, step back, and make sure that’s where you’ll want them to go. Then, using appropriately waterproof hardware and brackets, install the mounting hardware in that location. It’s a good idea to use LED house number lights so you don’t have to worry about hardwiring—and, in addition, LEDs will also last longer.
