Partsam 2.5" Round Amber LED Side Marker Lights — 10-Pack, 13-LED, Flush-Mount, Waterproof

Partsam 2.5" round amber 13-LED marker lights are DOT-approved, waterproof, flush-mount clearance/side marker lamps sold in a 10-piece kit with rubber grommets and pigtail wiring.

These compact amber LED lights replace small incandescent marker lamps on trailers, trucks, RVs and other commercial vehicles. Each sealed unit packs 13 LEDs behind a micro-reflex faceted lens to boost visibility while maintaining a low-profile 2.5" diameter footprint. The kit includes rubber grommets and two-pin pigtails for a straightforward flush installation and is built to resist water intrusion for demanding road and tow conditions.

How do these lights improve visibility on trailers and trucks?

The 13-LED array and faceted reflector increase light output and spread compared with a single-bulb marker. That combination makes the lamp more noticeable at night and in low-light driving situations without changing vehicle wiring. LEDs also provide consistent illumination and faster response than incandescent equivalents.

• 13 high-efficiency LEDs for brighter, uniform light
• Micro-reflex faceted lens enhances visible surface area
• Amber color meets standard marker/clearance signaling expectations

What is involved in installing the Partsam 2.5" marker lights?

Installation is designed to be simple: press each lamp into the supplied rubber grommet and connect the two-prong pigtail to existing 12V wiring. No screws are required for a flush-mount setup, although a small cutout matching the grommet diameter is necessary. If the grommet feels stiff, gentle heat will make insertion easier.

• Standard 2.5" cutout fits included rubber grommet
• Two-prong pigtail wires for quick electrical hookup
• Flush mount—no bezel or screws required for most installs

Are these marker lights durable enough for towing and marine use?

The housing and lens are sonically sealed into a single unit to prevent moisture entry and protect the internal circuit board and diodes. With an IP67-style waterproof rating, the units withstand exposure to rain, road spray and temporary submersion, making them suitable for boat trailers and other wet environments. The robust construction helps reduce maintenance and replacement frequency compared to unsealed lamps.

• Sonic-sealed housing prevents water and dust infiltration
• IP67-grade protection tolerates temporary submersion
• Compact, impact-resistant design for rugged road use

Will these lights fit my vehicle and where are they commonly used?

The 2.5" diameter is a common size for side marker and clearance lamps and fits many trailers, flatbeds, RVs and trucks. They are often used on air cleaner light bars, cab and sleeper kits, bumpers, rear panels and other small mounting points where a low-profile amber marker is required. Compatibility with OEM wiring is straightforward thanks to the standard 2-prong connector format.

• Commonly used on trailers, flatbeds, RVs and commercial trucks
• Fits many Kenworth, Peterbilt and Freightliner accessory locations
• Standard 12V operation with two-prong pigtail connector

Who is this for: The Partsam 10-piece amber 2.5" LED marker light kit is intended for fleet managers, trailer owners, RV enthusiasts and DIY mechanics who need compact, reliable, DOT-approved marker and clearance lamps. It’s a practical upgrade for anyone replacing incandescent markers, outfitting a trailer for towing or adding low-profile signaling lights to trucks and specialty vehicles.
