Partswcgg 2.5in Round LED Trailer Marker Lights, 13-LED 12V — Flush-Mount, IP67 Waterproof

Partswcgg 2.5" Round LED trailer marker lights are flush‑mount, 13‑LED amber and red reflectors designed for 12V trailers and trucks with IP67 waterproof protection.

These compact, flush‑mount round marker/clearance lights combine a faceted miro‑reflex reflector with 13 bright LEDs to improve side and clearance visibility on trailers, trucks, UTVs and similar 12V vehicles. Sonically sealed with an IP67 rating, the lights are built to withstand road splash and brief submersion while fitting into a small 2.5" inner diameter opening with a rubber grommet for a tidy installation.

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

The multi‑faceted reflector paired with 13 LEDs intensifies light output for clearer visibility from different angles. They’re designed specifically to increase detection by other drivers in low light and daytime conditions without drawing excessive current from a 12V system.

• 13 LEDs behind a miro‑reflex faceted reflector for amplified output
• Available in amber (side/clearance) and red (rear/clearance) colors
• Made for 12V electrical systems common on trailers and trucks
• Low current draw suitable for battery and vehicle wiring

What are the mounting and wiring requirements for installation?

These marker lights are flush‑mount and use a rubber grommet so you press the lamp into a pre‑drilled hole—no screws required. Wiring is simple: black is positive, white is negative; prepare a hole around 2–2/3" and the stated outer/inner diameters to ensure a snug fit.

• Drill a 2–2/3" hole, insert rubber grommet, press light into place
• Outer diameter ~3.5", inner visible diameter ~2.5", height with grommet ~1"
• 2‑prong pigtail: black (positive) and white (negative)
• Flush mounting eliminates the need for external fasteners

Are these lights waterproof and durable enough for trailer use?

Yes — each unit is sonically sealed and rated IP67, meaning it’s protected against dust ingress and can tolerate temporary immersion. The housing and lens are built for road conditions, resisting moisture and the vibration typical on trailers and utility vehicles.

• Sonically sealed housing and lens for reliable waterproofing
• IP67 rating for dust protection and immersion resistance
• Durable construction suited to trailer and truck environments
• Designed to resist road splash, dust, and vibration

Can one light serve as both a side marker and a clearance light?

These 2.5" LED units are designed to function as either a side marker or a clearance light, but not both at once from the same lamp. For legal or functional setups that require both side‑marking and front/rear clearance functions, install two separate lights—one dedicated to each role.

• Works as either a side marker or a clearance light, not both simultaneously
• Install separate lamps when both functions are required on the same panel
• Sold in sets including amber and red options for correct placement
• Follow local lighting regulations for side and clearance placement

Who this is for: These Partswcgg 2.5" round LED marker lights suit trailer owners, fleet operators, utility vehicle users and do‑it‑yourself mechanics who want compact, weatherproof, energy‑efficient marker and clearance lighting. They’re ideal when you need a low‑profile, easy‑install light that boosts visibility on semi trailers, utility trailers, horse trailers, pickup trucks, UTVs and similar 12V vehicles. If you need both side marker and clearance functions in the same area, plan on installing separate lights for each purpose.
