Partsam 5-Pack 17-LED Amber Torpedo Cab Marker Roof Lights — Chrome Housing, DOT-Compliant Heavy-Duty

These Partsam 5-piece amber torpedo cab marker lights are a heavy-duty, DOT-compliant roof running light assembly with 17 super-bright LEDs per unit designed for large trucks and commercial vehicles.

Fit and visibility are the two main priorities when replacing or upgrading cab marker lights on heavy equipment. Partsam's 17-LED amber torpedo-style lights come as a set of five, feature a chrome plastic housing, foam gasket for a secure seal, and two-wire hardwired connections. They are built to draw low current while providing crisp, fast-illuminating amber light to help your rig stay visible on highways and work zones.

How bright are these 17-LED Partsam cab marker lights?

The LEDs used in this assembly are high-efficiency diodes that light faster and appear brighter than comparable incandescent bulbs while consuming less power. Their amber color is chosen for maximum roadside visibility without overwhelming glare.

• 17 LEDs per unit for strong, even illumination
• Lower current draw compared with incandescent alternatives
• Quick response time for safer signaling and marker performance

Will these lights fit my truck’s cab roof or marker locations?

Partsam provides overall dimensions to help you verify compatibility before purchase. These units suit a wide range of heavy-duty vehicles but are not plug-and-play, so measure the existing mounting footprint and hole spacing prior to ordering.

• Overall dimensions: approx. 15.55" L x 3.54" H with a 9.84" hole distance
• Common fit for Kenworth, Peterbilt, Freightliner, Mack, International, and other heavy trucks
• Check existing cab marker size and hole locations to confirm fit

How are the lights installed and connected?

These Partsam lights are supplied with two leads for a hardwired installation—one positive and one negative—so some wiring skills or professional installation may be required. They are not a simple plug-and-play replacement; plan for secure mounting and proper sealing.

• Two-wire hardwired connection: black = positive, white = negative
• Includes heavy-duty foam gasket for a weather-tight seal
• Plastic chrome housing for a durable, clean finish

Are these lights durable enough for commercial use?

The assembly is intended for heavy-duty service with construction-grade materials and a gasketed design to withstand road vibration and weather exposure. While not indestructible, they are engineered to meet the demands of commercial truck fleets and specialty vehicles.

• Chrome plastic housing resists corrosion and impact
• Foam gasket reduces water intrusion and keeps the seal tight
• Designed for trucks, trailers, tractors, dump trucks, buses, boats, and special vehicles

Who this is for: This 5-piece Partsam 17-LED amber torpedo cab marker set is aimed at truck owners, fleet managers, mechanics, and restoration professionals who need a bright, energy-efficient marker solution with flexible fit options. Choose these lights if you operate Kenworth, Peterbilt, Freightliner, Mack, International, or similar heavy-duty vehicles and you’re comfortable with a hardwired installation and verifying measurements before replacing your cab markers.
