Jamarco 2-inch Round LED Trailer Marker Lights — 10‑Piece (5 Amber, 5 Red), Flush‑Mount 12V Sealed

These are a 10-piece set of Jamarco 2-inch round flush-mount LED trailer lights — five amber and five red — designed as side marker or clearance lights with rubber grommets and 2-prong pigtails.

Replace or upgrade your trailer’s visibility with a matched set of compact LED marker lights built for 12V vehicle systems. Each lamp uses four bright LEDs in a sealed housing rated for outdoor use, and the kit includes rubber grommets and wire pigtails to streamline installation. They fit most trailers, trucks, UTVs and other light-duty vehicles and provide a consistent color match between front/side and rear markers.

How do these lights mount and connect?

The lights are designed for flush mounting into a round cutout and come with rubber grommets to secure the lamp and seal against moisture. Wiring uses a simple two-prong pigtail: black for positive and white for negative, making them easy for DIY or professional installation.

• Mount type: flush mount with rubber grommet for a snug fit
• Cutout guidance: recommended hole ~2-5/16 inches
• Electrical: standard 2-prong pigtail (black = +, white = -)
• Outer diameter: 2.5 inches; inner lens diameter: 2 inches

Are these lights weatherproof and durable for road use?

Yes — each unit is sonically sealed into a single housing and lens assembly to protect the LEDs and wiring from moisture and dust. The construction and IP65-like protection make them suitable for typical road exposure, including rain and road splash.

• Sealed housing to prevent water ingress
• Durable polycarbonate lens and rugged back housing
• Designed for vibration-prone trailer environments
• Rated for 12V DC systems common on trailers and trucks

Which functions and placements are these lights intended for?

These 2-inch round LEDs are intended to serve either as side marker lights or as clearance lights depending on where you install them. They are color-coded — amber for side/front markers and red for rear/clearance positions — but a single lamp cannot simultaneously perform two distinct regulatory functions at once.

• Amber units typically mounted on sides or front marker positions
• Red units for rear clearance or side-rear marker positions
• Use separate lights if you need both side marker and clearance functions at the same location
• Universal fit for trailers, trucks, pickups, UTVs, and similar 12V vehicles

What should I know about installation and compatibility?

The set includes grommets and pigtails so you have what’s needed for a standard installation, but you may need to drill the recommended hole size and confirm polarity before finalizing connections. These lights run on 12V DC and are compatible with most trailer wiring harnesses used on light- and medium-duty vehicles.

• Confirm your vehicle’s voltage is 12V DC
• Drill a ~2-5/16 inch hole for optimal fit if existing holes don’t match
• Check polarity: black = positive, white = negative
• Hand-press depth affects final height (about 1 inch high with grommet)

Who is this for: This 10-piece Jamarco kit is aimed at trailer owners, small-fleet operators, DIY mechanics, and anyone who needs a coordinated set of compact, weather-resistant marker lights. It’s particularly useful when replacing faded or broken lights across multiple mounting points or when upgrading incandescent markers to longer-lasting LEDs.
