Frequently Asked Questions About Peterbilt Lighting

What years and models of Peterbilt trucks are these lights compatible with?

Most of our Peterbilt lighting products are designed to fit specific model ranges. The most common fitments include Peterbilt 379 (1987-2007), 389 (2008-present), 388 (2008-2015), and 567 (2014-present). However, compatibility varies by specific light type. For example, headlights for 379 models will not fit 389 models due to different housing designs. Always check the product description for your exact year and model, or contact our support team with your VIN number for guaranteed fitment verification.

Do I need special tools or professional installation for these lights?

Most Peterbilt lighting upgrades can be installed with basic hand tools including screwdrivers, socket sets, and wire crimpers. Headlight replacements typically take 30-45 minutes per side, while marker lights can be swapped in 10-15 minutes each. However, some LED conversions may require resistors or load equalizers to prevent hyper-flashing. We recommend having a multimeter handy to test connections. If you're uncomfortable with electrical work, professional installation typically runs $50-150 depending on the complexity of the lighting system.

What's the difference between halogen, HID, and LED options for Peterbilt trucks?

Halogen lights are the most affordable option and provide good visibility but have shorter lifespans (1-2 years) and higher power consumption. HID lights offer 2-3 times more brightness than halogen and last 3-5 years, but require ballasts and warm-up time. LED lights provide instant brightness, last 5-10 years, use minimal power, and run cooler, but have the highest upfront cost. For Peterbilt trucks, we recommend LED for frequently used lights like headlights and clearance markers, while halogen remains cost-effective for rarely used auxiliary lights.

Are these lights DOT approved and legal in all states?

All lighting products marked as DOT approved on our site meet Federal Motor Vehicle Safety Standards (FMVSS) requirements. However, some states have additional regulations regarding light color, brightness, and positioning. For example, colored accent lights may be restricted while driving in certain states. Headlights must maintain proper beam patterns to avoid blinding other drivers. Always verify your local and state regulations before installing aftermarket lighting. Our DOT-approved products will have the DOT marking stamped or printed directly on the lens or housing.

How do I prevent moisture buildup and ensure longevity of my Peterbilt lights?

Moisture intrusion is the number one cause of premature light failure. When installing, always use dielectric grease on electrical connections and ensure all gaskets are properly seated. Replace any cracked or hardened gaskets immediately. For LED lights, verify that vent caps (if equipped) are clear and functioning. Apply a thin bead of clear silicone around lens edges if you notice any condensation. Avoid pressure washing directly at light seals, and inspect lights monthly for any signs of moisture. Quality lights from reputable manufacturers typically include better sealing and last 3-5 times longer than budget alternatives.
