Trex® 24V 4x4" LED Post Cap Light

Add subtle, integrated lighting to your deck railing with the Trex® 4x4" LED Post Cap Light. Designed to complement Trex® 4" x 4" Composite Post Sleeves, this low-profile post cap creates a clean finished look during the day and adds soft, ambient illumination after dark.

The light features a 4.5" x 4.5" composite post cap sized to fit over compatible 4" x 4" Trex composite post sleeves. It is available in black, white, and vintage lantern finishes to coordinate with different railing designs.

Each post cap light includes a 6-inch lead and a 5-foot extension wire with threaded, water-resistant connectors for a secure outdoor connection. A UL Wet Location Listing supports reliable exterior use, while soy-free wire sheathing is designed to help minimize rodent attraction.
