Partsam 5-Piece 31-LED Amber Cab Marker Lights — Clear Lens, Chrome Base, IP67 Weatherproof

Partsam's 5-piece cab marker set are clear-lens, 31-LED amber roof running lights with chrome bases designed to replace incandescent clearance lights on heavy-duty trucks.

These replacement roof marker lights combine a high-density LED array, polycarbonate construction and IP67 sealing to deliver bright, weatherproof visibility for commercial trucks and trailers. They’re built as a universal fit for many makes—Peterbilt, Kenworth, Freightliner, Mack, International and others—and swap into common cab-marker mounting points to modernize older incandescent fixtures.

How bright are these cab marker lights for night driving?

The Partsam markers use 31 super-bright LEDs per housing, producing a highly visible amber signal that helps other road users spot your vehicle in low-light or poor-weather conditions. LEDs provide more consistent lumen output than aging incandescent bulbs and light up instantly for improved signaling.

• 31 high-intensity LEDs per lamp for strong amber illumination
• Instant-on LED response, no filament warm-up
• Clear lens for unfiltered brightness and wide-angle visibility

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

Yes—the lens and housing are polycarbonate and the unit is sealed to IP67 standards, which resists water and dust intrusion so it performs in rain, road spray and dusty environments. The chrome base adds corrosion resistance and a clean finish for commercial use.

• Polycarbonate lens and housing for impact resistance
• IP67-rated sealing for water and dust protection
• Chrome base for added corrosion resistance and easy cleaning

Will these fit my truck or trailer—what about installation?

These Partsam markers are offered as universal replacements intended for common roof marker applications on heavy-duty trucks, trailers, tractors and specialty vehicles. Before ordering, measure your existing cab marker footprint and verify mounting and wiring compatibility to ensure a straightforward swap.

• Universal compatibility: Peterbilt, Kenworth, Freightliner, Mack, International, Paccar and more
• Designed to replace incandescent cab marker and clearance lights
• Simple wiring: direct replaceable plug or hardwire to existing marker circuit

What maintenance or lifespan can I expect from these LED markers?

LEDs require minimal upkeep compared with incandescent bulbs; they run cooler and have longer operational life, reducing replacement intervals and downtime. The sealed, rugged construction lowers the need for routine servicing and helps maintain consistent performance under heavy use.

• Longer life expectancy than incandescent replacements
• Low heat output reduces housing stress and connector wear
• Sealed design minimizes corrosion and water-related failures

Who is this for: Fleet managers, owner-operators and maintenance techs looking to upgrade or replace worn incandescent cab markers with a bright, weatherproof LED option will find this 5-pack from Partsam suited to heavy-duty truck and trailer applications. If you operate or service Peterbilt, Kenworth, Freightliner, Mack, International or similar rigs and want a direct, durable LED replacement that improves nighttime visibility and reduces maintenance, this set is designed for that purpose.
