Project Source Brand Overhead Ceiling Light Fixture Installation-Model#0...

This Project Source brand overhead house light is fairly easy to put it in especially if its just a swap out for and older one. Just like in this case the existing wires and hole were already there.
The very first thing you want to make sure you do is turn off the power. Use a volt meter to verify that the power is off before you start as well just to make sure you've got the correct circuit. One thing I like to do as an added safety measure is to turn off the light switch as well. This way, if you've turned off the wrong circuit and happen to get unlucky enough to get a faulty volt meter, than you've got a third barrier from you getting shocked.
