Will these LED headlights fit my specific year Peterbilt 379?
Our LED headlights are designed to fit Peterbilt 379 models from 1987 to 2007. They use the standard 7-inch round mounting system and are direct replacements for the original sealed beam units. However, trucks manufactured before 1987 or modified with custom headlight buckets may require additional verification. We recommend checking your existing headlight mounting depth, which should be at least 3.5 inches for proper fitment.
Do I need to add resistors or modify my truck's electrical system?
Most of our LED headlights are plug-and-play compatible with your Peterbilt 379's existing wiring harness. However, some trucks may experience hyperflashing or dashboard warning lights due to the lower power draw of LEDs. In these cases, you'll need to install load resistors (sold separately) or an LED-compatible flasher relay. No cutting or splicing of factory wiring is required for standard installations.
What's the actual brightness difference compared to stock halogen lights?
Our LED headlights typically produce 3,000-4,500 lumens per light, compared to 700-1,000 lumens from standard halogen sealed beams. This translates to approximately 300-400% brighter illumination with a cleaner, whiter light output (5,700K-6,500K color temperature). The beam pattern is DOT-approved and designed to prevent blinding oncoming traffic while significantly improving your nighttime visibility.
How difficult is the installation process?
Installation typically takes 30-45 minutes per side for most drivers with basic tools. You'll need a Phillips screwdriver to remove the headlight bezels and retaining rings. The most common challenge is accessing the back of the headlight housing in tight spaces. Some drivers find it easier to remove the headlight assembly completely for better access. The LED units are heavier than stock lights, so handle them carefully during installation to avoid dropping them.
What warranty coverage do these LED headlights come with?
Our LED headlights come with manufacturer warranties ranging from 1 to 3 years depending on the brand. The warranty covers defects in materials and workmanship, including LED failure, moisture intrusion, and housing defects. Physical damage from impacts, improper installation, or modifications void the warranty. We recommend keeping your receipt and registering your product with the manufacturer for the fastest warranty service.
