Partsam 31LED Amber Cab Marker Lights — Waterproof IP67, Low‑Profile Chrome Base for Trucks

Partsam 31LED amber cab marker lights are compact, waterproof roof-running LEDs that replace incandescent clearance lights to increase night visibility on heavy trucks and trailers.

These Partsam cab lights combine a low-profile chrome base with 31 high-intensity amber LEDs beneath a clear polycarbonate lens rated IP67 for weather resistance. Designed as direct replacements for traditional incandescent cab marker and clearance lights, they suit a wide range of heavy-duty vehicles including Peterbilt, Kenworth, Freightliner, Western Star, Mack, International and other Paccar chassis. The plug-and-play form factor and sturdy construction make them a practical upgrade for fleets, owner-operators and equipment owners wanting brighter, more reliable roof illumination.

How much brighter are these LEDs compared with incandescent markers?

The 31 super-bright LEDs produce a stronger, whiter amber glow that is more visible at distance and in poor weather than equivalent incandescent bulbs. Because LEDs generate directional light and higher lumen output per watt, they improve conspicuity without drawing excessive current from your vehicle.

• 31 LEDs per housing for greater light spread
• Lower power draw than incandescent alternatives
• Sharper amber signature improves recognition by other drivers

Are these lights durable enough for heavy-duty and all-weather use?

Yes — each unit uses a polycarbonate lens and sealed housing built to IP67 standards, providing protection from dust and immersion in water for short periods. The chrome base and robust sealing keep moisture and road debris out, extending service life in rain, snow and highway spray.

• IP67 waterproof rating for heavy rain and washdowns
• Polycarbonate lens resists impact and UV fading
• Chrome base adds corrosion resistance and a finished look

Which vehicles and mounting styles are compatible with this Partsam cab marker light?

These top-roof clearance lights are intended as universal replacements for many heavy truck makes and models, including Peterbilt, Kenworth, Freightliner, Western Star, Mack and International. They’re commonly used on cabs, trailers, tractors, dump trucks and specialty vehicles; verify your existing marker dimensions and mounting holes before ordering to ensure a proper fit.

• Compatible with many Paccar-based trucks and other heavy-duty fleets
• Commonly replaces incandescent cab marker and clearance lights
• Measure your current fixture for hole spacing and depth to confirm fit

What should I expect during installation and maintenance?

Installation is straightforward for standard cab marker openings: remove the old light, connect the wiring harness, and fasten the Partsam unit to the roof with supplied hardware. Because LEDs run cooler and last longer than filaments, expect reduced maintenance and fewer replacements over time.

• Simple bolt-and-wire replacement for standard marker openings
• No frequent bulb changes thanks to long-life LEDs
• Regular visual checks recommended after heavy impacts or prolonged exposure

Who is this for: These Partsam 31LED amber cab marker lights are aimed at fleet managers, owner-operators and equipment owners seeking an affordable, durable upgrade from incandescent markers. They’re suited to anyone operating heavy-duty trucks, trailers, tractors or specialty vehicles who wants clearer roof-level illumination, lower power consumption and minimal ongoing maintenance.
