Jamarco 6.5" Oval Amber LED Side Marker & Mid-Ship Turn Signal - 2-Pack, 24-LED Sealed

These Jamarco 6.5" oval amber LED lights combine side marker/clearance and mid-ship turn signal functions in a water-tight, 24-LED housing for trailers and large vehicles.

Replace faded or slow incandescent markers with this two-piece set of oval amber LED lights from Jamarco. Built to fit standard semi-trailer side slots, each unit uses a three-wire pigtail for easy hookup and a built-in reflector to enhance visibility. The polycarbonate lens resists impact and weather, while the low-current LEDs light faster and run cooler than traditional bulbs.

How do these lights improve visibility and safety?

The amber polycarbonate lens includes a reflective element that increases perceived brightness when light hits it, and 24 high-power LEDs provide clear, fast-signaling for turn and marker functions. Faster response time and higher contrast help other drivers notice your vehicle sooner.

• Built-in reflector behind the lens for added retro-reflectivity
• 24 bright LEDs deliver consistent light output
• Amber color meets common visibility expectations for side/mid-ship signals
• Sealed construction prevents moisture from dimming output

What wiring and functions are included, and how do they connect?

Each light includes a standard 3-prong pigtail with color-coded wires for quick installation. The wires separate the ground, low-brightness marker function, and high-brightness turn signal so you can restore both clearance and mid-ship signaling from a single unit.

• White wire: chassis ground connection
• Black wire: low-brightness side marker/clearance output
• Red wire: high-brightness turn signal output
• Designed to fit common trailer side mounting cavities using supplied rubber grommet

Will these lights fit my truck or trailer footprint?

The lights are oval and measure 6.5 inches, matching many standard side-marker mounting openings on trailers and large vehicles. They come with a black rubber grommet intended for universal fit; however, verify your mounting hole dimensions before ordering to ensure a snug, weatherproof installation.

• 6.5-inch oval dimension to match common trailer slots
• Rubber grommet for flexible fit and vibration isolation
• Compact profile suitable for buses, tractors, dump trucks, ATVs and trailers
• Two-unit pack for left/right or spare replacement

How durable are these LED markers in real-world conditions?

Jamarco designed these markers with sealed housings and a rugged polycarbonate lens to resist water, dust and road debris. The LEDs draw low current and produce less heat than bulb-based designs, which helps extend service life under heavy-duty use.

• Watertight sealed assembly prevents moisture intrusion
• Polycarbonate lens resists impact and UV degradation
• LEDs lower electrical load and run cooler than incandescent bulbs
• Reflective elements maintain visibility even when unlit

Who is this for? Fleet operators, owner-operators and DIY mechanics who need a reliable, bright replacement for incandescent side marker and mid-ship turn signal lights will find this Jamarco 2-pack practical. It's especially useful for semi-trailers, dump trucks, buses, tractors, off-road rigs and utility trailers where standard 6.5" oval marker slots are used. If you want quicker signaling, lower electrical draw, and a weatherproof housing that installs with a simple 3-wire hookup, this pair offers a straightforward upgrade.
