Partsam LED Trailer & RV Side Marker Lights 4" 14‑Pack (7 Amber/7 Red), DOT Sealed Waterproof

Partsam 14-piece set of 4" sealed LED rectangle clearance and side marker lights provides DOT-compliant, waterproof illumination for trailers, RVs, trucks and campers.

This kit includes seven amber and seven red 4-inch oval-style LED marker lights with built-in reflex lenses, pre-wired two-conductor connections, and surface-mount hardware so you can replace or upgrade side marker and clearance lamps quickly. Each lamp contains six bright, energy-efficient LEDs in a sealed housing that resists moisture and road debris. The design integrates a reflector so a separate reflector is not required, and the lights work on standard 12V DC vehicle systems.

How do these lights install on my trailer or RV?

Installation is straightforward: each lamp mounts from the surface with included screws and requires a 3" approximate hole spacing for mounting. Wires exit the rear center of the housing—red for positive and black for ground—so you hardwire them into your trailer’s 12V circuit. Take care when tightening screws to avoid cracking the lens and seal the lens seam with silicone or RTV for extra protection.

• Surface-mount footprint: 4" x 2" x 1" housing size
• Mount hole spacing: roughly 3" center-to-center
• Wiring: two-conductor, red (+) and black (-)
• Included: 14 lights (7 amber front-side + 7 red rear-side) and mounting screws

What performance and safety features do these LEDs offer?

Each lamp contains six LED diodes that deliver brighter light while drawing less current than traditional incandescent bulbs, extending battery life and improving visibility. The sealed construction and reflex lens reduce the need for additional reflectors and help maintain performance in wet conditions. These lights are DOT approved, meeting regulatory standards for marker and clearance illumination.

• 6 high-efficiency LEDs per lamp for bright, low-power output
• Built-in reflex reflector eliminates separate reflector requirement
• Sealed, waterproof housing to resist moisture and road spray
• DOT certification for legal roadside use

Will these lights fit different vehicle types and mounting layouts?

Yes—the universal 4" oval dimensions match many existing camper and trailer marker light cutouts. They can serve as side markers, clearance lamps, identification lamps or general trailer lights on a wide range of 12V vehicles including RVs, fifth wheels, utility trailers, pickups and boats. Because the lens snaps on and off, replacing or relocating lights is possible with basic tools.

• Compatible with most 12V systems: RV, trailer, truck, camper, van, boat
• Functions: side marker, clearance, identification, and trailer light roles
• Snap-on lens allows removal for wiring or replacement
• Use silicone/RTV around the lens after installation for extra sealing

Who is this for: This 14-piece Partsam kit is aimed at owners and technicians who need a ready-to-install bundle to upgrade or replace marker and clearance lights across an entire vehicle or fleet. It’s especially useful for RV and camper owners who want matching amber front-side and red rear-side markers, trailer builders fitting multiple lamp positions, or anyone seeking DOT-approved, low-draw LED lighting that’s durable enough for road and weather exposure.
