Partsam 2.5" Round Red LED Side Marker Lights 10-Pack — DOT-Approved, IP67 Waterproof Flush-Mount

Partsam 10-pack 2.5-inch round red LED lights are compact, DOT-approved side marker and clearance lamps that include grommets and pigtails for quick flush-mount installation on trailers, trucks, and RVs.

These sealed 13-LED modules deliver a bright, modern signal in a small footprint and are built to withstand road spray and occasional submersion thanks to IP67 waterproofing. Supplied as a complete kit with rubber grommets and 2-prong wire pigtails, the set replaces older incandescent markers and fits most standard 2.5" mounting openings. The faceted reflector behind the lens increases perceived brightness while the sonic-sealed housing protects the LEDs and circuit board from moisture and debris.

How bright and visible are these 2.5" LED markers on the road?

The 13-diode array and mirrored reflector create a concentrated, highly visible red signal that reads well both in daylight and at night. They offer improved longevity and quicker illumination than incandescent bulbs, making them easier for other drivers to notice.

• 13 high-output LEDs per lamp for strong lumen output
• Faceted reflector enhances perceived brightness and spread
• DOT-approved color and intensity for legal roadside use

How simple is installation for trailers, trucks, or RVs?

Installation is designed to be straightforward: press the lamp into the supplied rubber grommet and plug the 2-prong pigtail into the vehicle wiring. No screws or complicated brackets are required for a flush mount, so a single person can typically complete multiple lights quickly.

• Includes rubber grommet and pre-wired 2-prong pigtail for each lamp
• Fits standard 2.5" round openings; no additional hardware needed
• Push-in flush mount eliminates drilling extra holes or screw hardware

Will these LEDs survive harsh weather and road conditions?

The lamps are sonically sealed and rated IP67, so they resist dust ingress and can tolerate temporary submersion — suitable for trailers that encounter splashes, heavy rain, or occasional immersion. The sealed design also prevents corrosion of the diodes and circuitry, which extends service life in salty or wet environments.

• IP67 waterproof rating for dust and temporary submersion protection
• Sonic-sealed lens and housing to block moisture and contaminants
• Durable polycarbonate lens and ABS housing resist impact and UV

Where are these small round markers commonly used?

These 2.5" round LEDs are versatile and fit many exterior locations on commercial and recreational vehicles. They’re frequently used as side markers, clearance lights, and decorative accent lighting on panels and light bars.

• Side marker and clearance positions on trailers and trucks
• Air cleaner light bars, cab and sleeper trim, bumpers, and rear panels
• Boat trailers and other vehicles exposed to water or harsh conditions
