Deck Lighting FAQs

Can I install my own deck lights?

Yes. The system is designed to be installed during the deck construction process, with underrail lights integrated into the railing assembly during installation. This makes it a great option for DIYers as well as professional installers, while ensuring the lighting is properly positioned and concealed within the finished railing system. For people looking to add lighting to their deck after a build or to an existing deck, post cap lights and riser lights are able to be added later.
