Partsam 10-Pack 2.5in Round Red LED Side Marker Lights — 13-LED DOT-Approved Sealed 12V

Partsam 2.5-inch round red LED marker lights are a DOT-approved, sealed 10-piece kit designed to replace incandescent clearance and side marker lamps on trailers and trucks.

These compact 13-LED markers offer bright, energy-efficient illumination in a small footprint, making them ideal where space is limited but visibility is critical. Each lamp is engineered for universal 12V vehicle applications, with a sealed housing for protection against water and road debris. The kit includes ten identical lights so you can refresh multiple mounting points or spare bulbs at once.

How bright and durable are these 13-LED markers?

The 13 high-efficiency LEDs deliver a strong, consistent red output that’s noticeably brighter than comparable incandescent bulbs while drawing less current. Their sealed construction shields the LEDs and wiring from moisture and grit to extend service life in harsh road environments.

• 13 LEDs per lamp for visible, even light spread
• Low power draw for efficient operation on 12V systems
• Sealed housing protects against water and dust ingress
• Durable polycarbonate lens resists impact and UV fading

Where can I use these marker lights on my vehicle?

These 2.5-inch round markers are sized to fit common mounting locations on trucks, trailers, RVs and utility vehicles. They can serve as clearance lights, side markers, or auxiliary accents wherever a small, round fixture is required.

• Commonly used on travel trailers, utility trailers, dump trailers and RVs
• Suitable for truck kits including cab accents, bumpers, and rear panels
• Works with many Class 8 vehicles such as Peterbilt, Kenworth, and Freightliner
• Compact design fits tight panels and light bars

How easy is installation and what electrical connections are needed?

Installation is straightforward: each lamp accepts an industry-standard two-prong plug (female receptacle built into the back). Grommet mounting is supported for many applications; note that the two-prong plug and grommets are commonly sold separately, so check your mounting hardware and connector inventory before you begin.

• Built-in two-prong female plug on the rear of each light
• Requires standard 2-prong male plug and grommet (both often sold separately)
• Simple replace-and-plug connection reduces wiring time
• Designed for 12V systems used in most trucks and trailers

Are these lights compliant and safe for road use?

Yes — the kit is DOT-approved for use as marker or clearance lights when mounted and wired correctly. The LEDs produce a consistent red color that meets visibility expectations for roadside applications, but proper installation and placement are necessary to maintain compliance.

• DOT-approved for marker and clearance applications
• Consistent red output for clear night and daytime visibility
• Sealed assembly helps prevent electrical shorts and corrosion
• Ten-piece kit lets you equip multiple positions at once

It's especially useful when you need multiple matching fixtures for axles, bumpers, sleeper kits or light bars and want a sealed, low-maintenance option that reduces current draw while improving on-road visibility.
