Peterbilt 389 Glider LED Headlights

Frequently Asked Questions About Peterbilt 389 Glider LED Headlights

Will these LED headlights fit my specific year Peterbilt 389 glider?

Our LED headlights are designed to fit Peterbilt 389 glider models from 2008 to present. They use the same mounting points and wiring connections as factory headlights, making them a direct replacement. However, some pre-2008 models may require minor modifications to the headlight bucket or wiring harness. We recommend checking your specific OEM with our customer service team if you have a model year between 2005-2007.

Do I need any special tools or professional installation for these LED headlights?

Installation typically takes 1-2 hours and can be done with basic hand tools including a Phillips screwdriver, 10mm socket, and wire crimpers. Most customers complete the installation themselves. The headlights come with plug-and-play connectors that match your factory harness. Some models may require a load resistor or anti-flicker module (sold separately) to prevent dashboard warning lights. Detailed installation instructions with photos are included with each set.

How much brighter are LED headlights compared to stock halogen, and are they DOT approved?

Our LED headlights produce approximately 3,600 lumens per bulb compared to 1,000-1,200 lumens from stock halogen bulbs - roughly 3 times brighter. All our LED headlights are DOT approved and SAE compliant for on-road use. They feature proper beam patterns that won't blind oncoming traffic when properly aimed. The 6000K color temperature provides crisp white light that significantly improves nighttime visibility.

What styles and finishes are available, and do they match factory chrome?

We offer LED headlights in chrome, black, and custom painted finishes. Our chrome options include both standard chrome and show-quality chrome that matches OEM Peterbilt trim. Popular styles include projector beam, reflector beam, and halo ring designs. Black options come in matte, gloss, and blackout finishes. Custom color matching is available for fleet orders of 10 or more sets.

What's the typical lifespan of these LED headlights, and what warranty coverage is included?

LED headlights typically last 30,000-50,000 hours of operation, compared to 500-1,000 hours for halogen bulbs. Under normal trucking conditions, this translates to 15-20 years of service life. All our LED headlights come with a 2-year warranty covering defects in materials and workmanship. The warranty includes free replacement for any manufacturing defects but does not cover damage from accidents, improper installation, or voltage spikes exceeding 32V.
