Partswcgg 2.5" Round Red LED Trailer Marker Lights 10-Pack — Flush-Mount, Sealed 12V

These compact red LED fixtures deliver visible, energy-efficient illumination for trailers, trucks, UTVs and other 12V vehicles. Each light uses 13 bright LEDs in a sealed housing with a rubber grommet and two-prong pigtail for straightforward flush installation. The lenses and housings are built to resist water infiltration so they hold up in wet road conditions and routine washdowns.

How do these lights mount and what hole size do I need?

These are designed for flush mounting with the included rubber grommets. The listed outer and inner diameters guide the cutout size so the lamp sits cleanly in the trailer skin.

• Outer diameter: 3.5" — overall flange size that rests against the panel.
• Inner diameter (cutout): 2.5" — the lamp body fits into this hole.
• Recommend drill/cutout: about 2–2.67" depending on panel thickness and grommet compression.
• Installed depth: roughly 1" with grommet compression; ensure clearance behind panel.

What wiring and electrical specs should I expect?

Each unit is built for standard 12V DC vehicle electrical systems and uses a simple two-conductor pigtail. Wiring follows common trailer color conventions, making integration with existing circuits straightforward.

• Voltage: 12V DC compatible with most trailers and light-duty vehicles.
• Pigtail: 2-prong wire (black = positive, white = negative) for quick splicing or connector hookup.
• Power: low-current LED array for reduced load on vehicle circuits.
• Use a dedicated light per function: one light for side marker or clearance per mounting location.

Are these lights weatherproof and durable enough for road use?

The lights are sonically sealed and rated to resist moisture intrusion, offering protection suitable for exposed trailer applications. The rugged lens and housing combination helps prevent fogging and water entry during typical outdoor exposures.

• Sealing: sonic sealing around lens and housing to minimize leaks.
• Water rating: IP65-grade protection against jets of water and dust.
• Lens/housing: rigid construction to handle vibration and road debris.
• LED array: 13 LEDs per unit for consistent brightness and long life.

Who is this product for? Installers, fleet owners, and DIY trailer owners who need a reliable, compact red marker or clearance light will find this 10-pack useful. It’s ideal when replacing multiple fixtures at once, outfitting trailers, utility trucks, horse trailers, UTVs and other 12V platforms. These lights suit buyers wanting simple flush-mounted installation, sealed housings for harsh conditions, and low-power LED performance. Note: each lamp can serve as either a side marker or a clearance light but not both simultaneously — use separate fixtures if you require both functions at one location.
