Partswcgg 14-Piece 4" Rectangular LED Trailer Marker Lights — Amber & Red, Reflex Lens Surface-Mount Kit

Partswcgg 14-piece set of 4" rectangular LED trailer marker lights provides bright, low-profile amber and red side/clearance illumination with built-in reflex lenses for easy surface mounting.

Upgrade your trailer, RV, camper, or truck lighting with this matched kit of fourteen 4" x 2" rectangular LED marker lamps. The package includes seven amber and seven red units, each engineered for surface mounting using the supplied stainless steel screws. These lights combine multiple LED chips for brighter, longer-lasting output and a snap-on reflective lens that integrates a reflector, so you don’t need a separate reflective tab.

How do these lights mount and what are the physical dimensions?

Each lamp is designed for simple surface installation and fits standard 3" mounting centers. The housing measures approximately 100mm long by 50mm wide by 25mm deep (about 4" x 2" x 1"). The kit includes stainless steel mounting screws, and the wiring is accessible from the front edge of the base for neat routing.

• Dimensions: 100mm x 50mm x 25mm (approx. 4" x 2" x 1")
• Mounting: surface mount with 2 stainless steel screws per lamp
• Hole centers: fits standard 3" spacing
• Wiring: two-wire hardwired connection (white = ground, black = positive)

What makes these LEDs different from standard marker lights?

Instead of single tiny diodes, each lens covers multiple LED chips which deliver stronger illumination and improved durability over incandescent bulbs. The integrated reflex lens removes the need to add separate reflectors, keeping the installation cleaner and compliant with visibility requirements.

• Multi-chip LED array for higher brightness and longer life
• Snap-on reflex lens provides both light diffusion and reflectivity
• Solid-state LEDs reduce maintenance compared with incandescent units
• Wires routed from the front side of the base for easier installation

Will these lights work on my RV, trailer, or truck?

The 4" rectangular format and universal wiring make this set compatible with most recreational vehicles, trailers, motorhomes, pickups, tractors, and commercial trucks. They function as side marker lights, clearance lights, or running/marker lamps where amber and red indications are required.

• Vehicle compatibility: RVs, campers, motorhomes, trailers, pickups, tractors, trucks
• Use cases: side markers, clearance lights, running lights, marker lights
• Color options included: seven amber and seven red lamps in one kit

What should I know about durability and service?

The housings and stainless steel fasteners are built for outdoor exposure, and the LED chips are selected for extended operational life compared with filament bulbs. If you encounter any issues, the seller offers customer support with a response promise to assist before or after purchase.
