Trex® Wedge Deck Rail Light

Wedge deck rail lights from TREX are easily installed on composite sleeves, as well as 2.5 in aluminum railing posts. Their sleek, understated construction blends right into the deck post during the day, and stands out at night. And like most TREX products, TREX post cap lights are manufactured in the USA. They beautifully match with the rest of the TREX deck lighting, as well as our high-performance line of composite decking and railing, and can be quickly installed with the TREX LightHub system. 24/7 weather-proof durability aluminum post cap lights are made with high-performance materials that can withstand years of tough weather. These lights are water and salt air resistant, even in the harshest climates. Because aluminum wedge lights are made by TREX, the world's #1 decking brand, they're also backed by a limited warranty. TREX covers the LED lights and housing for seven years of use.
