Partsam 2" Round Red 9-LED Trailer Side Marker Lights - 10-Pack, Sealed 12V Waterproof

Partsam 2-inch round red marker lights are sealed 12V LED clearance/side marker lamps (10 pieces) designed to replace incandescent lights and enhance visibility on trucks, trailers, RVs and tractors.

These compact 2" red LED lamps combine nine high-output diodes with a faceted reflector to produce a bright, consistent signal that’s visible in rearview mirrors and low-light conditions. Constructed for exterior vehicle use, the housings are sealed against moisture and road spray and are built to fit common 2" round cutouts used across heavy-duty and recreational vehicles. They arrive as a set of ten, intended to update multiple marker locations at once and to provide a uniform appearance along your trailer or truck sides.

How bright are these 9-LED Partsam marker lights?

Each lamp uses nine LEDs paired with a miro-reflex faceted reflector to increase perceived brightness and beam spread. The result is a punchy, clearly visible red signal that stands out in mirrors and at a distance without the warm-up time of incandescent bulbs.

• Nine high-efficiency LEDs per lamp for strong, steady output.
• Faceted reflector amplifies light and improves visibility angle.
• Instant on/off response—no filament delay.

Will these fit my truck, trailer, or RV wiring and mounting?

These 2" lights are designed for common marker and clearance light placements across trucks, semi-trucks, trailers, RVs and agricultural equipment. They run on standard 12V systems and use a two-prong wire pigtail connection—but note that round rubber grommets and pigtails are not included with the set.

• Standard 2-inch round size fits many common light panels and cutouts.
• Compatible with 12V vehicle electrical systems used on most trucks and trailers.
• Requires separate grommets and wiring connectors for sealed mounting.

Are these lights weatherproof and durable for road use?

Yes — Partsam’s marker lights feature sealed housings to keep out moisture, dust and road grime, which helps maintain consistent performance in wet conditions. The LEDs and reflector are enclosed behind a tough red lens designed for repeated exposure to road vibration and seasonal weather.

• Sealed construction protects LEDs from water and dirt intrusion.
• Resilient lens resists cracking from road debris and vibration.
• LED design reduces maintenance compared with incandescent bulbs.

What are practical uses for a 10-piece set?

A ten-pack allows you to update multiple side marker or clearance positions for a single trailer or to stock spares for a fleet. That makes it easier to achieve a consistent look and to replace worn incandescent markers across both sides and the rear of the vehicle.

• Refit both sides of a travel trailer or cargo trailer for symmetry.
• Keep spares on hand for quick roadside replacements.
• Upgrade older panels to more efficient LED lighting across multiple mounting points.

Who is this for: Professional drivers, fleet managers, RV owners and trailer DIYers who need reliable, visible side/clearance lights in a convenient 10-piece kit. If you want a straightforward LED upgrade for standard 2" round marker locations—improving brightness, longevity and road visibility—these Partsam sealed 12V lamps are a practical choice. Remember to source compatible rubber grommets and wiring connectors for a sealed, professional install.
