Jamarco 6.5" Oval Amber LED Side Marker & Mid-Ship Turn Signals — 2-Pack, 24-LED, Weatherproof

Jamarco's 2-pack 6.5" oval amber LED lights combine side marker/clearance lighting and mid-ship turn signal functionality in a single, weatherproof unit.

These oval amber LED lamps are designed for heavy vehicles and trailers that need a compact, bright, and durable lighting solution. Each unit houses 24 high-output LEDs behind an amber polycarbonate lens with a reflective surface to amplify visibility. The lights come with a black rubber oval grommet for a snug factory-style fit and a standard three-prong trailer wire pigtail (ground, marker, turn) for straightforward wiring.

How do these lights improve visibility for trailers and trucks?

The amber LEDs offer faster illumination and higher brightness than traditional incandescent bulbs, increasing the chance other drivers will notice your vehicle. The built-in reflective lens further boosts light return when illuminated or when external beams hit it.

• 24 high-power LEDs per unit for intense light output
• Amber polycarbonate lens with reflective surface for added visibility
• Faster response time than incandescent lamps for turn signaling
• Water-tight sealing keeps LEDs functioning in wet conditions

Will these fit my trailer or truck mounting location and wiring?

These 6.5" oval lamps are built to match common semi-trailer side marker and mid-ship turn signal cavities. They include a rubber grommet to help create a secure, vibration-resistant fit and standard three-wire pigtails for easy hookup to typical trailer wiring harnesses.

• 6.5" oval shape fits many standard side marker slots
• Black rubber grommet provides a sealed, snug installation
• Three-prong pigtail: white = ground, black = marker/clearance, red = turn signal
• Universal compatibility with trailers, semi-trucks, buses, tractors, ATVs, and dump trucks

How durable and weather-resistant are these LED marker lights?

The lamps are designed for heavy-duty environments; the LEDs are sealed against moisture and dust, and the polycarbonate lens resists impact and UV degradation. Because LEDs use less current and generate less heat than bulbs, they tend to last significantly longer under continuous use.

• Water-tight sealed LED assembly prevents moisture intrusion
• Polycarbonate lens resists cracking and fading from sunlight
• Low current draw reduces heat and extends component life
• Built-in reflector maintains visibility even when LEDs are off

How are these wired and what functions do the wires control?

Each lamp includes a three-wire pigtail that separates ground, marker brightness, and turn signal brightness so you can easily integrate it into existing vehicle circuits. The wiring allocation supports both steady marker/clearance lighting and a brighter, flashing turn signal output.

• White wire = chassis ground
• Black wire = low-brightness side marker/clearance light
• Red wire = high-brightness mid-ship turn signal
• Prewired pigtails simplify replacement and retrofit installations

Who is this for: these Jamarco 6.5" oval amber LED lights are suited for fleet managers, owner-operators, and DIY mechanics who need a compact, two-function replacement for mid-ship turn signals and side marker/clearance lamps. They work well on semi-trailers, box trucks, buses, agricultural equipment, dump trucks, and off-road vehicles where durable, bright, and fast-responding signaling and marker lighting are required. If you need straightforward wiring, weatherproof performance, and increased on-road visibility without changing mounting locations, this two-piece set is a practical option.
