The installation process for patio umbrella lights depends on the models you choose, and your first port of call should be the instructions provided by the manufacturer. Generally, you will need to detach the umbrella and remove it from its stand before attaching the lights. If you're installing disc lights, it' all a matter of attaching the lamp with the help of the clamp provided.
If you're installing strand lights, you need to attach the clips provided to each of the ribs, making sure you keep them away from the opening and closing mechanisms. For umbrella lights that use an electric plug to be connected to the electricity mains you also need to position the cord correctly so no one trips on it, which is especially important if you have children or pets.
