Peterbilt 579/587 Passenger Headlight
This United Pacific 35780 headlight assembly fits the passenger side of 2011 and newer Peterbilt 579 and 587 trucks. It delivers LED projection lighting with a sequential turn signal and daytime running light. The unit is built to genuine OEM quality and carries DOT/SAE approval for on-road use.
Patent-Pending Lens and Plug-In Wiring
A patent-pending lens design uses reflective turn-signal diffusers to widen visibility for other road users. The housing measures 29 by 17.5 by 17.5 inches and weighs 19.45 pounds. Installation is a direct plug into the existing wiring harness with no splicing or adapters required.
Verify Truck Model Year and Side Before Ordering
Confirm the vehicle is a 2011 or later Peterbilt 579 or 587 and that the passenger-side assembly is the one needing replacement. The part is not universal and will not fit other makes, model years or the driver side. Buyers needing a driver-side unit or a different truck application should look elsewhere.

Questions about this item
Does the 35780 headlight meet DOT/SAE approval for legal road use?
Yes, the assembly carries DOT/SAE approval, so it complies with federal lighting standards for on-highway operation.
What are the exact dimensions of the 35780 unit to confirm it fits a Peterbilt 579 or 587?
The housing measures 29 by 17.5 by 17.5 inches, matching the factory opening on 2011-plus Peterbilt 579 and 587 models.
How does the 35780 connect to the truck’s existing wiring harness?
It plugs directly into the factory harness; the key step is seating the connector fully until it clicks, otherwise the sequential turn signal and DRL functions will not activate.
