Partsam LED Cab Marker Lights 31-LED Amber — 5-Pack Waterproof IP67, Chrome Base

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.

How bright are these LED cab marker lights?

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.

• 31 super-bright LEDs per light for pronounced amber output
• Improved night and dawn visibility compared with incandescent
• Lower electrical draw and longer operational life

Are these lights weatherproof and suitable for heavy-duty use?

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.

• Sealed polycarbonate lens and housing for durability
• IP67-level waterproofing for heavy rain and washdowns
• Chrome base designed for rugged mounting surfaces

Which trucks and vehicles will these cab markers fit?

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.

• Universal fit for cab roofs, trailers, tractors, and specialty vehicles
• Great replacement option for incandescent-style marker lamps
• Sold as a 5-light set matching standard 5-marker applications

How easy is installation and what should I check before buying?

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.

• Check hole spacing and base footprint against your cab marker locations
• Confirm wiring connector compatibility or plan for simple wire splicing
• No special tools required for typical surface-mount installs

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.
