Partsam LED Side Marker Lights for Kenworth & Peterbilt — 2-Pack Amber/Clear Lens, Plug-and-Play Sealed

Partsam 2-piece LED side marker assemblies are sealed, plug-and-play amber/clear roof marker lamps built to replace the factory units on Kenworth T680/T880, Peterbilt 576 and similar PACCAR trucks.

These trapezoid-shaped side marker turn signal lights provide a direct-fit upgrade for PACCAR cab roofs and fenders, delivering brighter, longer-lasting illumination than many stock incandescent markers. Each kit includes both left and right assemblies with a clear lens that shines amber when lit, a weather-sealed housing, and a three-pin Weather Pack-style connector to match factory wiring. Designed to meet fit and function expectations, they help restore visibility, pass inspections, and modernize the look of your commercial truck without extra wiring or modifications.

How do these Partsam LED markers improve visibility on the road?

The LED modules produce a quick, bright amber output that is easier for other drivers to spot than dim or aged incandescent bulbs. Because LEDs light faster and maintain brightness over time, they enhance lane-change signaling and enhance your truck's presence in low-light conditions.

• 3 LED 3014 chips per assembly for crisp amber illumination
• Clear lens that reads amber when illuminated for high contrast
• Two-step brightness (high/low) for day/night visibility control
• Low current draw preserves electrical system and alternator load

Will these lights fit my Kenworth T680, T880, or Peterbilt 576 without modifications?

Yes — the assemblies are built as direct replacements designed to mate with the factory plug harness on many PACCAR models. The 3-pin Weather Pack-style connector matches OEM wiring, so installation is typically plug-and-play with no splicing required.

• Direct-fit dimensions: 6 1/3" x 2 1/8" x 1 2/3"
• Hole-to-hole mounting spacing: 4 1/4" to align with factory holes
• Universal left/right design for flexible placement
• 12-volt operation compatible with standard truck electrical systems

What construction and durability features should I expect from these assemblies?

Partsam uses a high-impact polycarbonate lens and a sealed housing to resist moisture, road salt, and vibration common in over-the-road use. The sealed design helps prevent corrosion and premature failure, extending service life compared with unsealed or poorly protected units.

• Weather-sealed housing to block water and contaminants
• High-impact polycarbonate for UV and impact resistance
• Low amp draw reduces strain on electrical components
• Robust mounting and OE-style fitment for long-term stability

How are these markers wired, and what functions do the pins provide?

The assemblies use a three-pin connector with separate circuits for high and low brightness plus a ground pin. That setup enables two-step brightness operation and straightforward integration with most truck signal circuits or multiplexed lighting systems.

• Middle pin serves as negative/ground
• Outer pins control high and low brightness modes
• Weather Pack-style connector mates to factory harnesses
• Plug-and-play installation minimizes downtime

Who is this for: These Partsam LED side marker assemblies are aimed at fleet owners, owner-operators, and mechanics who need reliable, inspection-compliant replacement markers for Kenworth T680/T880, Peterbilt 576, and other PACCAR trucks. They suit anyone wanting a durable, brighter, low-draw upgrade that installs quickly and restores proper signaling and visibility without custom wiring or expensive OEM parts.
