Peterbilt 587 Lights

Frequently Asked Questions About Peterbilt 587 Lights

Will these lights fit my specific year model Peterbilt 587?

Most aftermarket lights for the Peterbilt 587 are designed to fit model years 2011-2017. However, there can be slight variations in mounting points and wiring harnesses between early production (2011-2012) and later models (2013-2017). Always verify the specific year compatibility listed in the product description, and if you have a 2011-2012 model, double-check that the mounting brackets align with your existing holes before purchasing.

What's the difference between LED and halogen options, and which should I choose?

LED lights typically last 50,000+ hours compared to 1,000-2,000 hours for halogen bulbs, and they draw significantly less power from your electrical system. LEDs provide instant brightness and perform better in extreme temperatures. However, halogen lights are less expensive upfront and easier to replace individual bulbs. For daily drivers and long-haul applications, LED lights offer better long-term value despite the higher initial cost. Choose halogen if you prefer lower upfront costs and don't mind periodic bulb replacements.

Can I install these lights myself, or do I need professional help?

Most headlight and fog light replacements can be completed in 1-2 hours with basic hand tools. You'll typically need a socket set, screwdrivers, and wire crimpers for any electrical connections. The main challenges include accessing tight spaces behind the bumper for fog lights and properly aiming headlights after installation. Marker lights and interior lights are generally plug-and-play installations taking 15-30 minutes. If you're uncomfortable with electrical connections or lack the proper tools for headlight aiming, professional installation is recommended.

Are aftermarket lights DOT approved, and will they pass inspection?

Quality aftermarket lights sold for highway use should carry DOT (Department of Transportation) or SAE (Society of Automotive Engineers) approval markings. Look for these stamps molded into the lens or housing. Lights without these certifications may not pass state inspections and could result in citations. LED headlights must also maintain proper beam patterns to avoid blinding other drivers. Always verify DOT/SAE compliance in the product specifications before purchasing.

Why are my new LED lights flickering or showing error messages on my dash?

LED lights draw less current than traditional bulbs, which can trigger your truck's computer to think a bulb is out. This commonly happens with turn signals and marker lights. The solution is to install LED-compatible flasher relays or load resistors to match the original current draw. Some LED lights come with built-in resistors, while others require separate purchase. For headlights, ensure you're buying CANbus-compatible LEDs specifically designed for trucks with computer-controlled lighting systems.
