Partsam 31LED amber cab marker is a waterproof, high-visibility top roof running light assembly (5-pack) designed to replace incandescent cab marker lights on heavy-duty trucks.
These Partsam cab roof marker lights combine 31 bright LEDs with a sealed polycarbonate lens and chrome base to deliver long-lasting illumination and weather resistance for commercial rigs. They are sold as a set of five amber lenses with clear housings and are intended as a direct, modern replacement for older incandescent roof clearance lights on many makes and models of semi-trucks and specialty vehicles.
The 31 LEDs in each lamp provide a strong amber signal that improves visibility in low-light or poor-weather conditions without drawing excessive current. LEDs have a quicker response and longer lifespan than incandescent bulbs, making them a practical upgrade for fleets and owner-operators.
Yes — each unit features a polycarbonate lens and fully sealed housing rated to resist water ingress, so they can withstand rain and road spray. The IP67-grade construction protects the LEDs and electronics from moisture and dust, making them suitable for repeated use on the road.
These Partsam markers are marketed as universal heavy-duty replacements compatible with many common truck brands, including Peterbilt, Kenworth, Freightliner, International, Mack and models using Paccar components. Fitment depends on your existing cab marker footprint and mounting type, so measure your current lights before installing.
Installation is straightforward for most heavy-duty trucks — these lamps use standard mounting and wiring practices for cab marker lights. Before purchase, compare the length, hole spacing, and connector type of your existing marker lights to ensure a proper fit and to avoid drilling or rewiring modifications.
Who this is for: These Partsam 31LED amber cab marker lights suit fleet managers, owner-operators, and maintenance techs looking to upgrade from incandescent cab roof lights to a durable, energy-efficient LED solution. They are ideal for drivers of Peterbilt, Kenworth, Freightliner, Mack, International and similar heavy-duty vehicles who want clearer road presence, weather-resistant construction, and an easy replacement that matches standard five-marker roof configurations.
