Partsam 2-inch Red Trailer Marker Lights 10-Pack — 9-LED Sealed Waterproof Clearance & Side Marker Lamps

Partsam 2-inch round red marker lights are sealed, 9-LED clearance/side marker lamps sold in a 10-piece kit for 12V trucks, trailers, RVs and tractors.

These compact, bright red lamps replace older incandescent side markers and serve as clearance or side marker lights when mounted correctly. Each lamp houses nine LEDs and a faceted reflector to amplify visible output, packaged to withstand road and weather exposure with a sealed design suitable for typical 12V vehicle electrical systems. They’re offered as a cost-effective upgrade for fleets, individual trailers, and RV owners who need consistent, low-maintenance marker lighting.

How bright and durable are these 2" marker lights?

Each Partsam lamp contains nine LEDs paired with a miro-reflex style reflector to increase perceived brightness without higher power draw. The sealed housing helps keep moisture and road grime out, preserving the LEDs and electrical connections during routine use.

• 9 high-efficiency LEDs per light for clear visibility in mirrors.
• Miro-reflex faceted reflector to boost light throw.
• Sealed, weather-resistant housing for wet and dusty conditions.
• Designed for 12V systems common on trucks, trailers and RVs.

Will these lights fit my truck, trailer, or RV?

These are 2-inch round marker lights, a common size used on many truck and trailer light panels. They work as side markers or clearance lamps when mounted with the proper round grommets and wiring; note that rubber grommets and 2-prong wire pigtails are not included in the kit.

• 2" round diameter fits most standard marker cutouts and panels.
• Compatible with trucks, semi-trucks, utility trailers, dump trailers, travel trailers, vans and RVs.
• Often used on makes like Peterbilt, Kenworth and Freightliner when matching size and wiring.
• Requires separate grommets and two-prong pigtails for installation.

How do these lights compare to incandescent marker lamps?

Compared with incandescent bulbs, the nine-LED array offers longer expected lifespan, lower current draw, and faster illumination. The LED design reduces maintenance and improves reliability, while the reflector and lens design maintain a strong visual signature for other drivers.

• Lower power consumption than equivalent incandescent lamps.
• Longer operating life and reduced bulb changes.
• Quicker light-up response for immediate visibility.
• Faceted reflector provides contemporary look and improved reflectivity.

What installation and maintenance should I expect?

Installation is straightforward for anyone comfortable with basic trailer wiring: mount the light in the 2" hole, secure with an appropriate grommet, and connect to the 12V circuit. Because the lights are sealed and LED-based, routine maintenance is mainly limited to checking connections and lens cleanliness.

• Mounts into standard 2" round cutouts using a separate rubber grommet.
• Wire to 12V system using two-prong pigtails (not included).
• Periodic lens cleaning keeps visibility high; sealed body minimizes internal corrosion.
• Replace individual lamps from the 10-piece kit as needed for cost-effective upkeep.

Who is this product for? Fleet managers, trailer owners, RV enthusiasts and truck operators who want a reliable, economical LED upgrade for side marker and clearance lighting will find this 10-piece Partsam kit useful. It’s ideal for anyone replacing incandescent markers across multiple vehicles, building or refurbishing trailers, or standardizing marker lights across a fleet. Keep in mind you’ll need proper mounting grommets and wiring pigtails to complete installation; the kit focuses on the sealed LED lamps themselves for brightness and durability on the road.
