Partsam 5PCS 17 LED Amber Torpedo Cab Marker Lights – Roof Running Top Lights for International, Kenworth, Peterbilt, Freightliner, Mack | Heavy Duty DOT Compliant

Overview

Upgrade your fleet’s visibility with Partsam’s 5-pack of 17‑LED amber torpedo cab marker lights. These top‑mounted markers offer a bright, uniform glow that helps improve conspicuity on the highway while you’re signaling your position. Built for heavy‑duty trucks and large vehicles, they’re designed to withstand daily wear with a rugged chrome housing and a resilient foam gasket.

Compared with traditional incandescent markers, these LEDs draw less current, generate less heat, and light up quickly for immediate signaling. The amber color follows common marker light conventions, making your vehicle more noticeable from the sides and rear during daytime and nighttime driving. The 12‑volt system ensures compatibility with most fleet electrics, and the heavy‑duty construction aims to provide long‑term reliability in demanding on‑road conditions.

Key Benefits and Real‑World Use

• Low power draw and cooler operation: LED technology reduces load on the electrical system while delivering bright amber signaling.
• Rapid illumination: LEDs light faster than traditional bulbs, helping other road users notice your vehicle sooner.
• Durable chrome housing with foam gasket: A rugged exterior plus a moisture‑resistant seal supports longer life in harsh environments.
• Universal heavy‑duty fitment: Suitable for trucks, trailers, tractors, semi‑trailers, dump trucks, buses, boats, and other special vehicles.
• DOT compliant branding: Helps meet established signaling standards while upgrading your fleet’s visibility.

Fitment, Specs, and What’s Included

The set comprises five amber cab marker lights tuned for heavy‑duty trucks. Each light is crafted with the Watermelon Grakon 1000 style amber LED array and is paired with a chrome housing for a professional, high‑visibility look. Overall dimensions are approximately 15.55 inches long by 3.54 inches high, with a mounting hole distance of about 9.84 inches. Before purchasing, please compare these measurements to your current cab marker to confirm a proper fit.

Package includes: 5 cab marker lights. These lights are not plug‑and‑play; they arrive ready to be hardwired into your vehicle’s electrical system. White wires serve as negative and black wires as positive, providing a straightforward wiring approach for installers familiar with 12‑V truck lighting.

Installation Tips and Practical Notes

• Plan your wiring paths in advance and ensure clean connections to minimize weather exposure.
• Use the included foam gasket to help seal out moisture at the mounting site.
• Verify clearance and mounting pattern against existing markers to avoid interference with other hardware.
