This D.I.Y. Advice is part of a series How to build your deck

Step by Step Instructions

1 Mark out where your lights will go
2 Drill holes for your lights
3 Install your deck lights
4 Connect to power
  • Step 1. Mark out where your lights will go

    Remove the top board of your decking so that you have access to the back of the board you’re installing the light in. Then mark out your lights along the board. Make sure they are evenly spaced out. Just keep in mind where your power cord is and the length of the cable when deciding where the lights will go.
  • Step 2. Drill holes for your lights

    Before you start drilling, make sure there is nothing like cables or pipes behind the board. Now you’re ready to drill your holes. Choose the drill spade bit that matches up with the deck light that you’ve bought. Make sure the drill bit clears the light and the pins that hold it in as well by a couple of millimetres.
  • Step 3. Install your deck lights

    Put the lights inside the holes you’ve drilled. Connect the cord at the back of the light with the loom socket. You’ll need to screw in a cap at each connection, which will create a waterproof seal. 
  • Step 4. Connect to power

    Once you’ve connected the lights together to the loom, you’ll need to connect the cable to the transformer. Then plug the transformer into a switch and you’ll have power for your deck lights. Make sure your transformer isn’t placed where it can get wet. Replace the boards that you removed and you’re ready to enjoy your lights.
