Why choose an LED cab marker

• Brighter output with faster illumination to help convey signals sooner.
• Lower current draw and cooler operation compared with older incandescent markers.
• Simple upgrade path from existing incandescents without changing core wiring in most setups.
• Durable construction designed for demanding road conditions and weather exposure.

Key features and compatibility

They are commonly used on heavy-duty fleets from brands like Kenworth, Peterbilt, Freightliner, Mack, International, and PACCAR, among others. Note that for certain Kenworth W900 cab lights, a modification may be required to achieve an ideal fit.

• Size and mounting: 5 inches by 3.74 inches with a mounting hole; screws are not included. Please verify the cab marker opening before purchase.
• LED count and color: 17 amber-yellow LEDs arranged to provide broad visibility while using less power than incandescent markers.
• Regulatory note: DOT compliant design to help support compliant lighting standards on the road.

Real-world use and benefits

In everyday operation, the Partsam cab markers can provide a noticeable amber signal at dawn, dusk, or night, contributing to improved conspicuity from the side and above. The LEDs offer immediate response when illuminated and turned on, while consuming less energy and generating less heat than traditional markers. This combination may support smoother electrical performance and reduced maintenance over time.

For fleets updating aging rigs, these markers present a practical upgrade option. Keep spare markers on hand for quick swaps at the yard or after a roadside stop, helping to minimize downtime while maintaining a consistent exterior look across a fleet.
