Partsam 6" Amber LED Side Marker & Turn Signal Lights — 2-Pack, 18-LED Waterproof Surface Mount for Trailers RVs

Bright, waterproof amber side marker and turn-signal lights: a 2-piece, 6-inch, 18-LED surface-mount set from Partsam that combines running/clearance illumination with a higher-brightness turn-signal function for 12V trailers, RVs, trucks and campers.

These Partsam lights provide a compact, low-current LED solution to replace older incandescent side markers and auxiliary turn signals. Each sealed housing contains 18 LEDs and a built-in reflector, and arrives hardwired with three function wires so you can use a low-brightness mode for marker/running light and a high-brightness mode for turn or auxiliary signaling. The rugged plastic body and included mounting screws make surface installation straightforward on trailers, motorhomes, boats and utility vehicles.

How do I wire these lights for running and turn signals?

Wiring is simple because each lamp is pre-wired with three conductors for distinct functions. The white lead is ground, the black lead provides the low-brightness running/marker light, and the red lead switches to high brightness for turn or auxiliary signaling.

• White wire: ground connection to vehicle chassis.
• Black wire: connect to running/clearance light circuit.
• Red wire: connect to turn-signal or brake/aux circuit for high-intensity output.

Will these lights fit my trailer or RV—what are the size and mounting specifics?

Each lamp measures approximately 6 inches long by 2.4 inches wide and 2.4 inches high, a common footprint for side marker applications. They are surface-mount fixtures and include screws for quick attachment to a flat body panel, making them suitable for many trailer and RV installations where flush-mount holes aren’t available.

• Overall dimensions: 6" L × 2.4" W × 2.4" H (approx.).
• Surface-mount design with included mounting screws for straightforward installation.
• Compact profile fits utility trailers, campers, motorhomes, and trucks.

How bright and durable are the LEDs compared with incandescent lights?

These units use 18 LEDs per lamp for a bright, consistent output that lights faster and draws less current than incandescent bulbs. The LEDs are sealed within a waterproof housing to resist moisture and impacts commonly encountered on roads and at campsites.

• 18 LEDs deliver stable, high-visibility amber illumination.
• Lower current draw and reduced heat versus incandescent bulbs.
• Water-tight sealed construction for weather resistance and shock tolerance.

Can I use these lights on different vehicle types and in what applications are they best?

Yes—these lamps are designed for universal 12V systems and suit a wide range of vehicles. They work well as side clearance/marker lights, mid-turn signals, auxiliary warning lights, or running lights on trailers, RVs, trucks, and specialty vehicles.

• Compatible with 12V electrical systems on trailers, RVs, campers, trucks and more.
• Good for travel trailers, boat trailers, utility trailers, horse trailers, and motorhomes.
• Also useful as auxiliary or replacement turn/marker lights on custom builds.

Who is this for: Owners, fleet managers and DIY enthusiasts who need reliable, low-maintenance exterior lighting for 12V trailers and recreational vehicles. If you want a straightforward surface-mount replacement that gives clear running illumination plus a brighter signal mode, this two-piece Partsam set is built for easy wiring, long LED life and dependable weather resistance without rewiring complicated harnesses.
