Partsam Glass Watermelon Side Marker Lights 2-Pack — Clear Lens Red LED, Sealed IP65 for Kenworth/Peterbilt/Freightliner

Partsam 2-piece glass "watermelon" side marker lights are a patented, sealed LED assembly that combines bright red turn-signal output and low-brightness side-marker illumination in a compact bezel for semi trucks.

These replacement marker lights pair a clear glass lens with a metal bezel and high-powered LEDs to deliver eye-catching starburst illumination while resisting water, dust and road debris. Designed to fit many popular heavy-duty truck models — including Kenworth, Peterbilt and Freightliner — the two-wire harness uses white as ground, black for low-brightness side marker, and red for high-brightness turn-signal output, so installation is straightforward for most standard 3-wire systems.

How bright are these lights and what pattern do they produce?

The integrated LEDs produce a very bright, starburst-style beam through the glass lens that increases visibility at range and in low light. The clear lens maximizes light dispersion while the red LEDs ensure a recognizable signal color for turn and marker functions.

• High-powered LED for strong red output
• Clear glass creates a radial starburst pattern
• Two brightness levels: low for marker, high for turn signal
• Designed to enhance side and corner visibility

How do I wire and install the Partsam watermelon lights?

Wiring is simple: white wire is ground, black wire provides low-brightness side marker power, and red wire supplies high-brightness turn-signal power. The unit’s bezel and sealed glass make it suitable for flush or surface mounting on bumpers, air cleaners, marker pods or underglow locations.

• White = ground; black = side marker (low); red = turn signal (high)
• Fits standard mounting holes on many heavy trucks
• Sealed assembly reduces need for extra gaskets
• Includes two lights in the package for paired replacement

Are these lights weatherproof and durable for highway use?

Yes — each light uses a sealed glass lens and metal bezel rated to IP65, which keeps out most dust and protects against low-pressure water jets. That construction helps the light stand up to road grime, salt spray and typical roadside exposure.

• IP65-rated sealing against dust and water spray
• Metal bezel for impact resistance and secure mounting
• Glass lens resists UV haze and scratching better than some plastics
• Suitable for bumper, marker, and underbody placements

Will these fit my truck model and where can I mount them?

These universal-style LED marker lights are offered as replacements compatible with many semi-truck models, including common Freightliner, Kenworth and Peterbilt mount points. They are compact and versatile, so you can fit them on bumpers, air cleaners, marker pods or underglow arrays as needed.

• Universal fit for most heavy trucks and utility vehicles
• Direct replacement option for Kenworth, Peterbilt, Freightliner
• Works for custom installs on bumpers and accessories
• Sold as a 2-piece set for left/right applications

Who is this for: drivers, fleet managers and truck builders who want a durable, high-visibility marker and turn-signal solution that installs quickly and resists weather and road debris. These Partsam glass watermelon lights are ideal for owners replacing worn or cloudy markers, customizing show rigs with a distinctive starburst glow, or upgrading older incandescent lamps to brighter LED performance without complex rewiring.
