What Is a Piling Cap Light?
A piling cap light also called a marine piling light or dock piling cap light is a durable, waterproof lighting fixture installed on top of dock pilings. It combines two essential functions: protecting your pilings from moisture, UV exposure, and birds, while also illuminating your dock area for better visibility and safety.
These lights are commonly found on residential docks, marinas, and waterfront walkways. Most are built from UV- and corrosion-resistant marine-grade materials and are powered by either 12V DC or solar systems. With options like dusk-to-dawn sensors, 360° illumination, and color-changing RGBW LEDs, piling cap lights add both style and functionality to your dock.

-
