LIMICAR Welded Steel Trailer Light Boxes with 6-inch Oval LED Lights — IP67 Sealed, Black Powder-Coated

This all-in-one lighting kit pairs welded steel light boxes with bright 6-inch oval LEDs and 2-inch marker lights to give trailers, trucks, RVs and specialty vehicles a durable, weatherproof rear lighting solution. The lights are factory-sealed for waterproof performance and come with pigtails for a simple hardwire connection. Whether you weld the boxes directly to a frame or bolt them on, the kit is built to resist dust, water and road debris while providing clear signaling on the road.

How does this kit improve visibility and signaling on the road?

The 6-inch oval LEDs deliver high-contrast light output for brake, turn and tail functions while the included 2-inch marker lights add side and clearance visibility. LEDs respond faster than incandescent bulbs, helping other drivers notice braking and turning earlier. The kit’s sealed housings protect light output from moisture and dirt, preserving brightness over time.

• 6" oval LED lamps for stop, turn and tail functions
• 2" LED marker lights for side/clearance visibility
• IP67 sealing prevents moisture and dust intrusion
• Steel light boxes protect lamps from impact and corrosion

How do I install these welded steel light boxes on my trailer?

Installation offers two common options: weld the steel boxes directly to any frame member for a permanent fit, or bolt them on using factory holes or custom brackets. Each light has a 2‑wire sealed pigtail; match wires color-to-color and test functions before final mounting. For secure waterproof performance, ensure seams are welded or fasteners are sealed after aligning the lights.

• Hardwire pigtails: white = ground; red = high/stop/turn; black = low/tail
• Weld boxes onto frame for permanent mounting or bolt on for removability
• Use the included rubber grommets to protect wiring at entry points
• Test lights before final paint or seam sealing

What makes these light boxes durable and weather resistant?

The light boxes are made from heavy-duty steel with a black powder-coated finish that resists corrosion and abrasion. The LED lamp units are fully sealed and rated IP67, meaning they can withstand immersion and keep out dust. Welding the boxes onto the frame reduces gaps where water can enter, and the included rubber grommets add extra protection where wires pass through metal.

• Heavy-gauge steel construction with black powder coat for longevity
• IP67-rated sealed LED units for moisture and dust resistance
• Welding technology and rubber grommets improve waterproof integrity
• Sealed pigtails reduce electrical exposure to elements

Will these lights fit my vehicle and what vehicles are compatible?

The design is universal for most commercial and recreational trailers and many special vehicles. They’re suitable for rear frame mounting on trailers, trucks, RVs, horse trailers, dump trucks and other platforms up to and beyond 80 inches wide. Compatibility is broad because the kit includes common LED lamp sizes and simple color-coded wiring for quick integration with standard trailer wiring harnesses.

• Universal fit for trailers, trucks, RVs, caravans, and specialty vehicles
• Direct weld-on or bolt-on mounting to rear, side, bottom, or top frame
• Includes two 6" oval LEDs and two 2" marker lights with pigtails
• Color-coded wires simplify connection to standard harnesses

Who is this for? This LIMICAR kit is made for professional fabricators, fleet owners, and DIY trailer builders who need a robust, weatherproof rear lighting solution. It’s especially useful when a permanent, protected installation is required—such as welded frame mounting on trailers, commercial trucks, horse trailers, or RV conversions—while still allowing bolt-on flexibility for modular setups.
