Partswcgg LED Trailer Marker Lights 14Pc 4" Rectangular Set — Amber & Red, Reflex Lenses, Surface-Mount

Partswcgg 14-piece set of 4" rectangular LED trailer marker lights provides bright, replaceable-reflex lens clearance and side marker illumination for trailers, RVs, and trucks.

These compact 4 x 2 x 1 inch LED marker lights combine amber and red lenses, built-in reflex reflectors, and surface-mount hardware to modernize exterior lighting on campers, motorhomes, utility trailers, pickups and commercial rigs. The set includes seven amber and seven red fixtures, each hardwired with two color-coded leads for straightforward installation and maintenance-free LED operation.

How do these LEDs differ from older incandescent side marker lights?

LEDs use multiple LED chips to emit cleaner, more consistent light with lower current draw and longer expected life than incandescent bulbs. Partswcgg fixtures include six LED chips per lamp and snap-on reflex lenses so you get increased visibility without frequent replacements.

• Six LED chips per lamp for brighter, more even illumination
• Lower power consumption than incandescent bulbs
• Snap-on, replaceable lens with integrated reflex reflector
• Durable hardwired connection for reliable operation

What are the dimensions and mounting options?

Each light measures approximately 100mm x 50mm x 25mm (4" x 2" x 1") and fits standard 3" mounting centers. The housing is made for surface mounting and ships with stainless steel screws, making it suitable for wood, metal or composite mounting surfaces.

• Overall size: 4" L x 2" W x 1" H — compact for tight mounting locations
• Mounting centers compatible with many trailer patterns (about 3")
• Includes stainless steel screws for corrosion resistance
• Wires exit from the front side of the base for neater routing

How are they wired and what should I know before installation?

Each LED marker has two wires: white for ground and black for positive power. Installers should confirm vehicle wiring polarity and use appropriate connectors or sealant to protect splices from moisture and corrosion.

• Hardwired with two leads: white = ground, black = positive
• Wire exits from front side of base for flexible routing and tidy mounts
• Use waterproof connectors and dielectric grease on exposed splices
• Polarity check recommended before final mounting to avoid damage

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

These rectangular LED markers are designed as universal replacements for many RVs, campers, trailers, trucks and tractors. The mix of amber and red lenses meets common side-marker and clearance placement needs across a wide range of vehicle types.

• Universal fit for RVs, motorhomes, campers, trailers, pickups and commercial vehicles
• Amber units for front/side; red units for rear/side clearance applications
• Replaceable lenses let you refresh reflectivity without replacing the entire lamp
• Suitable as upgrades from incandescent side marker lights

Who is this for: This 14-piece Partswcgg kit is ideal for vehicle owners and fleet managers who want a cost-effective, low-maintenance update to exterior side marker and clearance lighting. It suits DIY installers and professional shops replacing faded reflectors or upgrading to LEDs across multiple mounting points on trailers, campers, RVs, pickups and commercial equipment.
