Choose Peterbilt LED Headlights

Find heavy-duty Peterbilt LED lights and assemblies to replace your Peterbilt 379 headlight setup. We carry complete, plug-and-play drop-in replacements for both primary configurations:
  • Factory Dual 4x6 Rectangular: Maintain your OEM-equivalent appearance while upgrading to modernized LED performance. Available in chrome or blackout housings, these setups replace your aging factory buckets with high-output projector beams and halo running lights.
  • 7-Inch Single Round Conversions: Retrofit your 379 to mimic the old-school, classic aesthetic of the Peterbilt 359. Our conversion kits include the complete headlight bucket, mounting arms, and 7-inch LED lamp assemblies required to execute the swap flawlessly.

Why Upgrade to Aftermarket Peterbilt LED Assemblies?

Replacing cracked, yellowed factory halogens with complete Peterbilt 379 headlights provides immediate performance benefits for owner-operators:
  • SmartHeat Winter Technology: Because LEDs run cooler than halogens, snow and ice can accumulate on standard lenses. We offer heated LED headlights equipped with SmartHeat grids that automatically melt winter buildup for uninterrupted visibility.
  • Enhanced Beam Patterns: Modern LED projector lenses focus light precisely down the highway, widening your field of view without blinding oncoming traffic.
  • Integrated Custom Lighting: Consolidate your lighting. Many of our aftermarket assemblies feature built-in dual-color halo light rings and integrated amber LED turn signals.

Replacement Buckets, Bezels & Visors

If your internal structure is failing but your lamps are functional, we stock the supporting hardware to rebuild your front end. We carry dual lamp buckets, retaining rings, and replacement H4 harnesses. To complete your custom chrome package, pair your new lighting setup with aftermarket headlight bezels, hooded visors, and turn-signal covers. These cosmetic upgrades perfectly complement additional exterior accessories like Peterbilt 379 hood trim, Peterbilt 379 grilles, and Peterbilt 379 bumpers.

Frequently Asked Questions About Peterbilt 379 Headlight Upgrades

What are the clearance requirements for modified or custom 379 headlight buckets?

While standard 1987–2007 Peterbilt 379 housings accept drop-in replacements, trucks running customized aftermarket buckets require physical clearance verification. A modern LED headlight assembly requires a minimum internal mounting depth of 3.5 inches to properly seat the rear heat sinks and cooling fins without binding against the housing wall.

What is the safest method for installing heavier LED assemblies in a 379?

Because LED projector assemblies carry significantly more physical weight than factory glass sealed beams, navigating the tight internal cavity of a 379 headlight bucket can be challenging. To prevent dropping and damaging the new lens, the most efficient installation method is to completely unbolt the headlight assembly arm from the hood. This allows for unrestricted rear access to safely seat the heavier unit and secure the retaining rings.

What does the manufacturer warranty cover on aftermarket LED assemblies?

Our Peterbilt 379 LED headlights feature manufacturer warranties ranging from 1 to 3 years, depending on the specific brand. This coverage protects against manufacturing defects, internal LED diode failure, and weather-seal moisture intrusion. Warranties are strictly voided by physical impact damage, unauthorized wire splicing, or improper installation. We highly recommend retaining your commercial invoice and registering the product entity with the manufacturer to expedite any future claims.
