Partsam 2-inch Round LED Clearance Marker Lights, Red 10-Pack — Sealed 4-LED Waterproof

Partsam 10x Red 2" round sealed LED clearance marker lights are compact, DOT-approved side/clearance indicators with 4 high-efficiency LEDs, grommets, and pigtails for fast, waterproof installation.

These 2-inch round LED trailer lights replace incandescent markers with a brighter, longer-lasting option built for rugged vehicle use. Each sealed unit is sonically welded to resist water and dirt, and the kit supplies matching rubber grommets and two‑wire pigtails so you can mount and wire them quickly into standard 12V DC systems. Designed for trailers, trucks, buses and utility vehicles, the lights meet DOT clearance/marker dimensions while offering low current draw and easy maintenance.

How are these lights installed and what tools do I need?

Installation is straightforward: drill a 2-5/16" hole for the recessed mount, push the lamp through the included grommet, and connect the two pigtail wires (black negative, red positive) to your vehicle wiring. No special crimping is required if you use quick-connects; silicone sealant can be added for extra protection.

• Required hole size: 2-5/16" for recessed fit.
• Wiring: two-wire pigtail (red = positive, black = negative).
• Mounting: rubber grommet included for a flush, vibration-resistant seal.
• Optional: quick connectors, screwdriver, and sealant for long-term weatherproofing.

What makes these different from standard incandescent marker lights?

LEDs deliver brighter illumination with far lower power consumption and much longer operational life than incandescent bulbs. The sealed, submersible housing prevents moisture-related failures common with older lights and reduces maintenance intervals.

• Low amp draw extends battery life and reduces fuse replacements.
• 4 high-efficiency LEDs provide clear visibility for other road users.
• Sonically sealed housing and lens for waterproof performance.
• DOT-approved form factor for compliance with clearance/marker regulations.

Will these fit my vehicle—what sizes and voltages are supported?

These markers are built for 12V DC systems and are widely compatible with trailers, trucks, buses, and many utility vehicles. Dimensions are optimized for a recessed 2" lamp opening with an outer bezel of 2.5" to cover cutouts cleanly.

• Voltage: 12V DC only—standard for road and utility trailers.
• Outer diameter: 2.5"; inner (lamp) diameter: 2.0".
• Installed depth: approx. 0.78" with grommet for flush mounting.
• Includes industry-standard 2-prong plug and pigtail for common wiring harnesses.

How durable are these lights in wet or off-road conditions?

The units are sonically sealed and rated to be submersible, making them suitable for wet roads, heavy rain, and splash-prone environments. The robust lens and housing resist vibration and impact common on trailers and heavy-duty vehicles.

• Waterproof, sonically sealed construction for immersion resistance.
• Durable lens resists cracking and fogging under road conditions.
• Flush grommet mount reduces snagging and physical wear.
• LEDs are less susceptible to shock-related failure than filaments.

Who is this for? Installers, fleet managers, and vehicle owners who need reliable, low-maintenance marker lights for trailers, trucks, and utility vehicles will value this kit. It suits anyone replacing failing incandescent markers, upgrading to LED for better visibility, or outfitting new builds where DOT-approved clearance/marker lighting is required. The 10-piece pack especially benefits fleets and multi-axle trailers that require multiple matching markers for compliance and consistent appearance.
