What years of Peterbilt 387 are these LED headlights compatible with?
Our LED headlights are designed to fit Peterbilt 387 models from 2000 to 2010. However, we recommend verifying your truck's specific headlight configuration before ordering, as some late-model years may have variations. The mounting brackets and wiring harnesses are identical to OEM specifications for these model years.
How difficult is the installation process and what tools do I need?
Installation typically takes 30-45 minutes per side and requires basic hand tools including a Phillips screwdriver, 10mm socket wrench, and wire strippers if you're adding optional accessories. The LED headlights are plug-and-play with your existing wiring harness - no cutting or splicing required for basic installation. Some customers report needing to adjust the headlight aim after installation, which requires a flat surface and measuring tape. Professional installation is not necessary, but we recommend having a helper to hold the light assembly while you secure the mounting screws.
What's the actual brightness difference compared to stock halogen headlights?
Our LED headlights produce approximately 3,200 lumens per light on low beam and 4,800 lumens on high beam, compared to the 1,000-1,200 lumens found in stock halogens. This translates to about 300% more usable light on the road. The 6000K color temperature provides a crisp white light that reduces eye strain during night driving. Many customers report being able to see road signs and obstacles 200-300 feet farther down the road compared to their original lights.
Are these DOT approved and legal for highway use?
Yes, all our Peterbilt 387 LED headlights carry DOT approval markings and meet FMVSS-108 standards for on-road use in all 50 states. Each light is stamped with the DOT certification number on the lens. They feature proper beam patterns that won't blind oncoming traffic when properly aimed. We include beam pattern alignment instructions with each set to ensure your lights meet legal requirements and pass state inspections.
How long do these LED headlights actually last compared to regular bulbs?
Our LED headlights are rated for 50,000 hours of continuous use, compared to 500-1,000 hours for standard halogen bulbs. In real-world trucking conditions, this typically means 8-10 years of service life with normal use. The aluminum housing and polycarbonate lens are designed to withstand road vibration, temperature extremes from -40F to 185F, and are IP67 waterproof rated. Each unit includes a 3-year warranty against defects, and we stock replacement parts should you need them after the warranty period.
