Partsam 31-LED Amber Cab Marker Light — IP67 Waterproof Roof Running Clearance Lamp, Chrome Base

Partsam 31LED Amber Cab Marker Light is a waterproof, high-visibility roof running/clearance lamp designed to replace incandescent cab markers on heavy-duty trucks.

These low-profile marker lights combine a chrome base, clear polycarbonate lens and 31 high-output LEDs to improve side- and front-facing visibility for large vehicles. Built to IP67 standards, they resist water and road grime while fitting common mounting locations on cabs, trailers and specialty equipment. The design works as a direct visual upgrade from older incandescent markers, and the universal mounting footprint fits many Peterbilt, Kenworth, Freightliner, Mack, International and Paccar applications.

How bright are these 31 LED cab marker lights?

Each module houses 31 concentrated amber LEDs arranged to deliver a broad, consistent glow that’s easy to see in low light and urban conditions. The intensity improves recognition by other motorists and can reduce the need for additional auxiliary lighting.

• 31 high-output LEDs per lamp for wide-angle visibility
• Amber color optimized for clearance and marker applications
• Clear polycarbonate lens preserves brightness without yellowing
• Chrome base enhances reflection for added presence

Will these lights stand up to rain, road spray and washdowns?

Yes — the assembly is sealed with a polycarbonate lens and housed to meet IP67 waterproofing, letting it endure heavy rain, splashes and pressure wash cycles common in fleet use. The sealed construction also keeps out dust and salt, extending service life.

• IP67-rated sealing against water immersion and dust
• Polycarbonate materials resist impact and UV exposure
• Corrosion-resistant chrome base for harsh environments
• Fully sealed wiring points reduce failure risk

How do I install these on my truck or trailer?

Installation is straightforward when replacing similarly sized marker lights: match the footprint, connect the power and secure the mounting screws. Always verify fitment measurements and wiring compatibility for your vehicle before purchase.

• Designed as OEM-style replacements for many heavy-duty trucks
• Mounting requires matching hole pattern or minor drilling
• Simple wire connection to existing marker circuits
• Check dimensions against your current cab marker before ordering

What vehicles are these compatible with?

These markers are intended for large truck brands and heavy equipment, including Peterbilt, Kenworth, Freightliner, Mack, International and other Paccar platforms. They also suit trailers, tractors, dump trucks and specialty vehicles where a compact amber marker is needed.
