Partsam 3.8" LED Side Marker & Clearance Lights 20‑Pack — Amber/Red, DOT‑Approved, Waterproof

Partsam 20-piece set of 3.8" amber/red LED side marker and clearance lights provides bright, DOT-approved visibility for trailers, trucks, RVs, and more.

These low-profile LED marker lamps are built to improve vehicle visibility on the road while fitting a wide range of 12V vehicles. Each lamp contains six high-intensity LEDs in a sealed housing with pre-attached wiring and a peel-and-stick gasket for a quick, water-resistant installation. The kit includes 20 lights plus screws and foam tape bases so you can outfit multiple mounting points at once.

How bright and visible are these marker lights?

The lamps use six concentrated LEDs per unit that deliver strong, consistent illumination suitable for side markers, clearance lights, and signaling. They meet DOT standards for marker lights and are visible under motion and in low-light conditions without excessive power draw.

• Six high-intensity LEDs per lamp for clear visibility
• DOT-approved light output and color options (amber or red)
• Low current draw helps preserve vehicle battery life
• Even illumination pattern reduces dark spots

How easy is it to install these on my trailer or RV?

Installation is straightforward: each lamp comes with pre-attached red (positive) and black (negative) wires, plus a peel-off gasket for wet locations and a foam tape base for flush mounting. You can surface-mount or screw the units in place using the included hardware for a secure fit.

• Pre-wired with red (positive) and black (negative) leads
• Peel-and-stick gasket for waterproof sealing
• Includes screws and foam tape base for multiple mounting options
• Low-profile design minimizes snagging and wind resistance

What vehicles and applications will these lights work with?

These 3.8" LED markers are designed for universal 12V use, so they fit trucks, trailers, RVs, campers, motorcycles, golf carts, and many specialty vehicles. They work equally well as side markers, turn indicators, clearance lights, running lights, brake lights, decorative accents, or underglow points.

• Compatible with most 12V systems: trucks, trailers, RVs, campers
• Suitable for boats, snowmobile trailers, and golf carts with proper mounting
• Multi-purpose: marker, indicator, running, brake, and decorative light
• Mount almost anywhere on the vehicle exterior

Are these lights weatherproof and durable enough for road use?

The sealed housing and included gasket provide water resistance appropriate for exterior mounting, while the compact, low-profile shell resists impact and reduces wind drag. They’re intended for routine road conditions, though proper installation and periodic inspection will maximize longevity.

• Sealed lens and peel-off gasket for water resistance
• Durable plastic housing resists chips and cracks from debris
• Foam tape base cushions mount points and reduces vibration
• Includes screws for a secure mechanical attachment

If you’re upgrading visibility on work trailers, equipping a new camper, or replacing worn side markers across several vehicles, this kit gives you DOT-compliant illumination, easy wiring, and the hardware to complete several installs at once.
