Partsam LED Cab Marker Lights 5-Piece Amber Torpedo — Chrome Housing, DOT-Compliant Bright 17-LED Assemblies

Partsam 5PCS 17-LED amber torpedo cab marker lights are a set of heavy-duty, DOT-compliant roof running lights designed to replace worn cab markers on trucks and commercial vehicles.

These low-current 12V LED assemblies deliver brighter, faster illumination than incandescent bulbs while generating less heat. Housed in chrome plastic with a robust foam gasket, the five-piece kit fits many heavy-duty makes including Kenworth, Peterbilt, Freightliner, International, Mack and more. The lights are hardwired (not plug-and-play) and supplied with two-wire leads for a straightforward positive/negative connection.

Will these lights fit my truck roof or cab marker holes?

Check the overall length and hole spacing before ordering: the assembly measures about 15.55" long and 3.54" high with a hole center spacing of roughly 9.84". This universal-style housing is built to match common cab marker layouts on heavy-duty trucks, but confirm physical dimensions against your existing unit.

• Overall length ≈ 15.55 inches
• Height ≈ 3.54 inches
• Hole center distance ≈ 9.84 inches
• Designed for common heavy-duty makes (Kenworth, Peterbilt, Freightliner, International, Mack)

How do I install these LED cab marker lights?

Installation requires hardwiring: the lights are not plug-and-play. Each lamp has two leads — white for negative (ground) and black for positive (hot) — that you connect to your vehicle's lighting circuit. Use proper sealing and secure mounting to maintain weather resistance.

• Supplied with two-wire leads (white = negative, black = positive)
• Hardwired installation — basic electrical skills recommended
• Use silicone sealant or proper gaskets when mounting to prevent water ingress
• Confirm vehicle wiring and fuse protection before connection

What are the light and build characteristics?

Each assembly contains 17 amber LEDs arranged for high visibility and quick response time compared with incandescent lamps. The chrome plastic housing and heavy-duty foam gasket add durability on road-facing surfaces while helping to resist vibration and moisture.

• 17 amber LEDs per lamp for bright, efficient output
• Chrome plastic housing for corrosion resistance and style
• Heavy-duty foam gasket included for improved sealing
• 12V input; lower current draw and reduced heat vs incandescent

Are these lights compliant and suitable for commercial use?
