Jamarco 6.5" Oval LED Side Marker Lights 2-Pack Amber, Sealed Polycarbonate Lens 24-LED

These Jamarco 6.5" oval amber LED lights are a two-piece combination side marker, clearance lamp and mid-ship turn signal designed to fit standard semi-trailer and heavy-duty vehicle openings.

If you need durable, bright amber markers that perform as both a low-intensity side/clearance lamp and a high-intensity mid-ship turn signal, this 2-piece set from Jamarco offers sealed LED illumination, a reflective polycarbonate lens and universal wiring for quick replacement on trucks, trailers and work vehicles.

How do these LED markers improve visibility on trailers?

The LEDs provide faster illumination and higher perceived brightness than incandescent bulbs while consuming less current. The built-in reflective lens increases visible output even when LEDs are off, helping other drivers spot your vehicle in low-light conditions.

• High-density 24 LED array for strong, uniform light.
• Reflective amber polycarbonate lens boosts passive visibility.
• Sealed, water-tight housing resists moisture and road spray.

What wiring and functions are included — can I install them myself?

Each lamp includes a standard 3-prong pigtail wired for ground, marker/clearance and turn signal functions. The color-coded leads make swapping a quick task for anyone familiar with trailer lighting systems.

• White wire: ground connection.
• Black wire: low-brightness marker/clearance function.
• Red wire: high-brightness turn signal output.

Will these lights fit my truck, trailer or specialty vehicle?

These 6.5" oval fixtures are intended to match common semi-trailer side lamp openings and grommets. Their universal dimensions and rubber grommet simplify retrofit on many heavy-duty applications.

• Fits most standard semi-trailer amber side marker slots.
• Suitable for trailers, semis, dump trucks, buses, tractors and off-road rigs.
• Includes black rubber oval grommet for secure mounting and vibration dampening.

How durable are the lenses and LEDs under road conditions?

The lens is molded from impact-resistant polycarbonate and the assembly is sealed to keep out water and dust. LEDs run cooler and last longer than incandescent bulbs, reducing maintenance and replacement frequency.

• Polycarbonate lens resists chips and UV degradation.
• Water-tight sealing prevents corrosion and short circuits.
• Low current draw reduces heat and strain on wiring harnesses.

Who is this for? This Jamarco two-pack is aimed at fleet managers, owner-operators, mechanics and DIY vehicle owners who need a reliable replacement for mid-ship amber turn signals and side/clearance markers. It’s a practical choice when you want a low-maintenance, bright LED upgrade that fits standard 6.5" oval cutouts and uses ordinary three-wire trailer wiring. If you maintain heavy trucks, trailers, agricultural equipment or off-road work vehicles and require weatherproof, high-visibility lighting that’s simple to install, this set is built for that use.
