While some composite deck lights are powered by solar, most of them are powered by a 12-volt transformer. Check out the comprehensive guide below that will aid you in mounting the holiday lights on your deck. Here, the focus will be laid on post cap lighting.

• Using a table saw, cut a 3/8 inch x 3/8 inch channel down through the center of the top surface of the top rail.
• Move the fence near to the blade in order to remove the center material after making your two outside cuts for the channel. Then mark the center of the top surface of each 3x3-rail post.
• Drill a 5-inch hole on the center of the rail post using a 1-inch diameter forstner bit. Placing the drill bit on the top rail channel, drill a 3/8 inch hole in the side of the 3x3 rail post towards the center hole.
• Leave 6 inches of excess wire above the post after pulling down the low voltage wires via the center hole. Next, run the wire down the side of the end rail post. To get the low voltage wires into the transformer, drill a hole through the deck floor.
• Using a wire stripper, strip the wire ends back by a few inches, and then align the wire polarity. The positive side is smooth black while the negative side is marked with white lettering.
• Connect the low voltage wires to the correct polarity by using a weatherproof wire nut. With two screws, screw the post cap light to the side of the post. Then finally, connect the low voltage wire located at the end post to the transformer.
