Yes, you can. This question comes up a lot for people who don’t want to spend a lot of money on energy and money. The easiest way to install multiple lights on one circuit is to create an in-wall socket that will accommodate several light bulbs at once. However, this method doesn’t last very long and usually requires constant maintenance as the sockets become outdated in time. Some people have recommended that you put two or more lights on the same circuit when you’re using multiple switches for control of those lights at the same time.
