Partsam Amber Cab Marker Lights 5-Pack — 6-LED Waterproof Truck Roof Clearance

Bright, waterproof amber roof marker lights with six high-output LEDs per lamp designed to upgrade truck visibility and replace worn cab clearance lights.

These Partsam cab marker lights are built for heavy-duty vehicles that need reliable, energy-efficient illumination on the roofline. Each lamp houses six LEDs inside a sealed polycarbonate body rated for wet conditions, making them suitable for long-haul trucks, trailers, and specialty equipment. The lamps are offered as a five-piece set and are intended as direct-fit replacement fixtures for many Freightliner and Volvo models, though wiring modifications are required for installation.

How bright are these amber cab marker lights on the road?

Each housing contains six high-output LEDs that deliver a focused amber glow to improve vehicle outline recognition at night and in low-visibility conditions. The LEDs are designed to energize quickly and produce steady illumination without filament warm-up.

• Six LEDs per lens for concentrated light output
• Amber color optimized for clearance/marker visibility
• Faster-on lighting compared with incandescent bulbs
• Low power draw to reduce electrical load

Will these lights survive rain, road spray, and snow?

The housings and lenses are constructed of durable polycarbonate and sealed against the elements, offering an IP65-class level of protection from water jets and dust. That makes them suitable for exposed roofline mounting where they will encounter rain, splashes, and seasonal road grime.

• Polycarbonate lens and housing resist impact and UV fading
• Fully sealed construction to block water ingress
• Corrosion-resistant materials for long-term exterior use

Are these lights compatible with my Freightliner or Volvo truck?

Partsam designed this five-pack as an exact-fit replacement for many Freightliner and Volvo cab marker applications, but they can also be used on other 12V trucks, trailers, tractors and specialty vehicles. Confirm lens shape and mounting hole spacing with your existing lights before ordering.

• Engineered to match common Freightliner/Volvo roof marker dimensions
• Works on most 12V heavy-duty vehicle electrical systems
• Can be adapted for trailers, dump trucks, semi-trailers and tractors

How difficult is installation and wiring?

These are not a plug-and-play kit; the existing plug must be cut and wires spliced to the new lamp leads. Wiring is straightforward: the black lead is positive and the white lead is negative (ground). Use proper connectors and sealant to preserve the waterproof rating after installation.

• Requires cutting the old plug and splicing wires
• Black wire = positive; white wire = negative (ground)
• Use heat-shrink or marine-grade connectors for a sealed splice
• Verify polarity and function before final mounting

Who this product is best for: Fleet owners, owner-operators, and maintenance teams who need rugged, low-power roof marker upgrades for heavy trucks and trailers. It's especially useful when replacing aged incandescent markers with longer-lasting LEDs on Freightliner or Volvo cabs, or when outfitting work rigs that face wet, dusty, or harsh road environments. If you prefer plug-and-play replacements, note that these units require basic wiring work to install; otherwise they deliver a bright, durable amber marker solution for commercial vehicles.
