Hey there, it’s Bryan “Bossman” Martin, coming to you from 4 State Trucks in Joplin, Missouri! We’re always on the lookout for innovative and high-quality products that will make our customers’ trucks stand out from the rest. That’s why we recently teamed up with MW Metalworks and their incredible line of lighting fixtures and wire harness covers.

What Sets Them Apart?

MW MetalWork has taken lighting to a whole new level both for the inside and outside of the truck. Their lighting solutions are remarkable due to their construction from high-quality thick billet aluminum. You can easily feel the durability and long-lasting nature of these light fixtures when you hold them in your hand. They truly lead the industry as the Cadillac of lighting due to their superior build and materials.

We’re stocking some more new products here at 4 State Trucks, check out these Sleeper Lights & Wire Harness Covers from the folks over at MW MetalWorks. Join Bryan “Bossman” Martin as he shines the light on these new products we have added to our inventory.

Dome Light Fixtures

MW MetalWorks offers several different dome light options such as a four-light fixture and a single Peterbilt dome light replacement. Both feature glass watermelon-style lenses with billet aluminum bases to give your Peterbilt cab and sleeper lighting a bit of an upgrade.

  • 4 Glass Watermelon Style Sleeper Lights With Billet Aluminum Base
    Here is a complete four-light fixture with an independent switch, mounted on a high-quality Billet aluminum piece.
  • Single Glass Watermelon Style Dome Light
    Many of us are familiar with dome lights that were commonly used in Peterbilt, Kenworth, and Freightliner trucks. In fact, Peterbilt still uses them quite often in the luggage compartments of their sleepers. This particular dome light is designed to replace those old dome lights in your sleeper, offering a more modern and efficient lighting solution.
  • Replacement Dome light for your cab and sleeper on your Peterbilt 379.
  • Another replacement cab and sleeper Peterbilt 379 Dome light.

Surface Mount Light Fixtures


You can use these glass cab light surface mount fixtures anywhere inside or outside on any vehicle that operates on a 12-volt system. They work great on, trailers, bass boats, or side-by-side as well.

What makes these lights really cool is that they are designed to accommodate any two-inch LED light, giving you the freedom to choose from a wide range of LED brands and colors. The twist feature on the back makes installation simple and the two-inch sealed beam design ensures long-lasting performance.

When you purchase these single glass cab light fixtures, you’ll receive two gaskets, a lens, a stainless bezel, an o-ring, hardware, and a pigtail.

Wire Harness Covers That Are Build To Last

If you own a Peterbilt 379, you’re likely familiar with the hood on the driver’s side firewall of your truck. The main wire harness cover from the factory is made of plastic, but over the course of 10 to 15 years, they tend to split and crack.

However, this particular Peterbilt 379 wire harness cover is different. It is made of thick billet aluminum, specifically designed to withstand the test of time. To further enhance its durability, the aluminum has been powder-coated with a wrinkle finish. With this upgrade, you can expect this wire harness cover to last for decades on the firewall of your Peterbilt.
