Partswcgg Trailer Light Kit — 6" Oval Red LED Tail Lights & 2" Round Side Markers, Welded Steel Boxes, Sealed Pigtails

Partswcgg's kit is a complete welded-mount steel housing set that includes 6" oval red LED tail lights, 2" round red LED side marker lights, rubber grommets and sealed pigtail connectors for a durable, weather-resistant trailer lighting solution.

This all-in-one kit supplies the metal mounting boxes plus the LED fixtures and wiring you need to install flush-mounted trailer taillights and side markers. The heavy-duty steel boxes arrive powder-coated in black and are pre-cut for easy grommet mounting; the LEDs are waterproof and come with sealed pigtails so you can hardwire them quickly. A one-year warranty backs the package for added peace of mind.

How does this kit simplify trailer light installation?

The assembly reduces custom fabrication and drilling: the steel boxes are pre-cut for the exact light dimensions and include grommets and sealed pigtails. That means fewer parts to source and less on-site trimming.

• Pre-cut openings for 6" oval tail lights and 2" round side markers
• Rubber grommets included for weatherproof flush mounting
• Sealed 2- and 3-prong pigtails for direct wiring to trailer harness
• Weld-on or bolt-on box design for quick attachment to frame

What are the light specifications and wiring details?

The kit includes two 6" oval tail lights with 10 red LEDs each and two 2" round marker lights with 4 red LEDs. The oval tail lights use a three-prong pigtail (white ground, red stop/turn/brake, black tail), while the round markers use a two-prong pigtail (black ground, red positive).

• Oval tail light dimensions: 7.25" L x 3.1" W, 10 red LEDs, 3-prong wiring
• Round marker dimensions: 2" diameter lens, 4 red LEDs, 2-prong wiring
• Grommet outer/inner diameters matched to each light for flush fit
• Waterproof lenses and sealed pigtails for outdoor use

Are the mounting boxes built to withstand road conditions?

Yes—the mounting boxes are fabricated from heavy-duty steel and finished with a black powder coat to resist corrosion and abrasion. They are sized to accept the included lights and leave room for wiring, making them robust for typical trailer applications.

• Steel box overall: 8.78" L x 3.92" H x 3.82" W
• Front oval cutout: 6.75" x 2.5"; side marker cutout: 2.25"
• 3/4" wire access hole for protected routing
• Weld-ready design; can also be bolted on depending on installation

What comes in the box and what tools will I need?

The kit ships with two welded-mount steel boxes, two 6" oval LED tail lights, two 2" round LED markers, corresponding rubber grommets, and sealed pigtail connectors. Basic wiring tools and either welding equipment or bolts and hardware are required to secure the boxes to your trailer.

• Included: 2 steel boxes, 2 oval tail lights, 2 round markers, 4 grommets, 3- and 2-prong pigtails
• Recommended tools: wire crimper, heat shrink or waterproof connectors, drill (if bolting), welder (optional)
• Installation steps: hardwire pigtails to harness, seat lights in grommets, weld or bolt box to frame
• Manufacturer warranty: 1 year

Who is this for? This Partswcgg kit suits trailer owners, fabricators, and repair shops that want a pre-sized, heavy-duty mounting solution with LED fixtures and sealed wiring included. It's particularly useful for utility trailers, horse trailers, small commercial trailers, and anyone replacing recessed or surface lights with a neat, weatherproof flush-mount setup.
