An outside lamp post is an excellent way to add increased security and safety to your home. But remembering to turn on the lamp post every night is easier said than done, and using a timer means that you always have to remember to adjust it for daylight savings. By installing an outside post lamp that has a built-in light sensor, you'll never have to worry about those concerns ever again. With a light sensor controlling the function of the light, it automatically turns on when the sun goes down and turns off when it comes back up. And best of all, wiring the fixture isn't that difficult to do.
Turn off the circuit in the electrical panel that powers the light that's currently installed on the lamp post.
Remove the top of the light fixture by removing the bolts with a screwdriver or the finishing caps with needle-nose pliers that hold it in place. Pull the top off and remove the bulb. If the light was recently on, wait for the bulb to cool before performing this step.
Loosen the bolts on the base of the lamp post fixture with a screwdriver. These bolts are what secure the fixture to the post. Once the bolts are loose, the fixture can be lifted off the post.
Test the wires inside the post with a touch-type voltage tester before you touch any of the wires with your hands. Press the button on the tester and touch the tip of it to each wire to make sure the circuit is dead. If the tester beeps or lights up, then the circuit is still live. Try additional breakers until you find the correct one.
Pull the wires out of the post until you find the wire connectors that connect the fixture wires to the feed wires. Disconnect the wire connectors to remove the fixture and bend the feed wires over the rim of the post to prevent them from falling back down inside.
Strip any necessary insulation from the ends of the wires both on the new fixture and the wires in the post using the wire strippers.
Connect the ground wire from the post to the ground wire on the new fixture with a wire connector.
Connect the white wire from the post with the white wire on the light fixture and the white wire on the light sensor. Make sure the wire connector is on tight and wrap the connection with electrical tape to help keep the elements from getting inside the wiring.
Connect the black wire from the post with the black wire on the light sensor. Make sure the wire connector is on tight and wrap the connection with electrical tape to help keep the elements from getting inside the wiring.
Connect the black wire from the fixture with the red wire on the light sensor. Make sure the wire connector is on tight and wrap the connection with electrical tape to help keep the elements from getting inside the wiring.
Push the wiring back down inside the post and set the fixture on top of the post. Secure it in place by tightening the bolts around its base.
Remove the top of the fixture according to the manufacturer's instructions and install a properly rated light bulb. Replace the top and turn the circuit back on.
Cover the light sensor with electrical tape so no light can get through, to test the installation. In a few seconds, the light should turn on. Remove the tape and after a few seconds, the light should turn off.
