Partsam 2" 4-LED Round Trailer Marker Lights 10-Pack (5 Amber / 5 Red) — IP67 Waterproof, DOT-Approved Flush-Mount

These Partsam 2" sealed 4-LED round clearance and side marker lights (5 amber, 5 red) are DOT-approved, IP67 waterproof, and include grommets and pigtails for a flush, reliable 12V installation.

Whether you're replacing worn incandescent markers or upgrading trailer lighting for visibility and durability, this 10-pack from Partsam provides a compact, low-power solution. Each lamp is sonically sealed with a reflex lens and a waterproof housing rated to IP67, designed to resist moisture and road debris while delivering years of LED life. The kit includes standard grommets and pigtails, so you can fit them into most 2" cutouts and wire them quickly with a simple two-wire connection.

How do these lights install and what cutout do they need?

These flush-mount markers are made to drop into a round grommet and be sealed against the mounting surface. The kit’s grommet and light assembly require a drilled hole slightly larger than the inner diameter so the grommet can seat snugly.

• Outer diameter of the light: 2.5 in.; inner diameter (lens) fits a 2.0 in. opening.
• Recommended drill hole: about 2.25–2.30 in. for proper grommet fit.
• Grommeted flange yields a 0.78 in. overall depth with grommet installed.
• Two-wire hookup: red for positive, black for negative—no extra ground required.

Are these lights durable enough for trailers, trucks, and outdoor use?

Yes. Each lamp is built for rugged road use and long operational life thanks to LED technology and a sealed housing. The sonically sealed assembly prevents water ingress, and the IP67 rating means brief submersion won’t compromise the unit.

• IP67 waterproof rating for protection against immersion and heavy splashes.
• Sonically sealed lens and housing to keep out dirt and moisture.
• LEDs rated for 30,000+ hours of service life under normal conditions.
• Reflex lens enhances visibility without additional reflectors.

Will these lights work with my vehicle’s electrical system?

They are designed for DC 12V electrical systems, which makes them compatible with most trucks, trailers, RVs and light commercial vehicles. The simple two-conductor wiring keeps installation straightforward and reduces the chance of wiring errors.

• Operating voltage: 12 volts DC — standard for trucks, trailers and RVs.
• Two-wire design: red = positive, black = negative (ground).
• Direct LED replacement for many incandescent marker lights, lowering power draw.
• DOT-approved lens and light configuration for legal road use where required.

What practical benefits come from using these LEDs versus older bulbs?

LED marker lights draw less current, resist shock and vibration better, and tend to last far longer than incandescent bulbs. That reduces maintenance stops, replacement parts on hand, and electrical load on the vehicle’s circuits.

• Lower power consumption compared with incandescent lamps.
• Improved shock resistance and reduced filament failure risk.
• Long service life minimizes replacements and downtime.
• Maintains legal marker/clearance signaling with DOT approval.

Who is this for: this Partsam 10-pack suits fleet managers, professional drivers, trailer owners, RV enthusiasts and do-it-yourself mechanics who need reliable, legally compliant side marker or clearance lighting. It’s especially useful when replacing multiple damaged lights at once or upgrading an older lighting system to a tougher, lower-maintenance LED option.
