In this instructional video, learn how to install a VOLT® deck light on a post. We’ll run the wire down through the post and out the back, then mount the fixture cleanly. This is a fairly simple do-it-yourself project for illuminating your deck or dock.

Step-by-Step Instructions

How to Install a Deck Light in a Post

Step 1: Remove the cap from from the post. Once removed, you’ll see the slots for running the wire down the post.

Before drilling into the post, determine where your connections will be located and how you'll get the wire out of the post.

Step 2: Before drilling into the post, determine where your connections will be located and how you’ll get the wire out of the post. You can use a coat hanger or a fiberglass wire pull rod, which can be found at any home supply store.

Step 3: Remove the screws from the railing bracket. This will free up the sleeve, making it much easier to access the wire.

Step 4: Mark the location of the hole you'll be drilling. Remember that the wire exits from the bottom of the fixture, so keep that in mind when deciding exactly how high or low on the post you would like your fixture to be placed.

Step 8: Cut off a piece of wire about 10 feet long and begin feeding it down the post until you feel it hit the bottom. By lifting up the post and creating a 2 to 3 inch gap, we can easily pull the wire through.

This will help with guiding the wire back out the slot that was just drilled. After you get it through, make sure to pull out all the slack.
