Peterbilt 389 Glider Lights

Frequently Asked Questions About Peterbilt 389 Glider Lights

Will these lights fit my specific year Peterbilt 389 glider kit?

Our Peterbilt 389 glider lights are designed to fit 2008-2015 model years. However, glider kits can vary depending on the builder and specific configuration. We recommend checking your existing light mounting points and comparing them with our product specifications. If you're unsure, contact us with your OEM or photos of your current setup, and we'll help verify compatibility before you order.

What's the difference between OEM-style and aftermarket LED options for my 389 glider?

OEM-style lights maintain the factory appearance with traditional halogen bulbs, while LED aftermarket options offer brighter illumination, longer lifespan (typically 50,000+ hours), and lower power consumption. LED lights generate less heat and are more resistant to vibration. The main trade-off is cost - LED options typically run 30-50% more expensive upfront but save money long-term through reduced replacement frequency and lower electrical load.

Do I need any special wiring or adapters to install these lights on my glider kit?

Most of our lights are plug-and-play with standard Peterbilt wiring harnesses. However, some glider kits may have modified wiring depending on the builder. LED conversions may require load resistors or flasher relays to prevent hyperflashing on turn signals. We include basic installation instructions with each light, and many products come with necessary pigtails or adapters. For custom builds, you may need additional connectors or wiring modifications.

Are these lights DOT approved and legal for highway use?

Yes, all lights in this category meet or exceed DOT FMVSS 108 standards for highway use. Each light is marked with the appropriate DOT codes for its function (SAE codes for side markers, turn signals, etc.). We only carry lights from reputable manufacturers that maintain proper certifications. Keep in mind that some states have specific requirements for light colors and positions, so verify your local regulations if you're considering non-standard configurations.

How durable are these lights compared to factory options?

Our replacement lights are built to match or exceed OEM durability standards. Most feature polycarbonate lenses that resist cracking better than older acrylic designs, with UV-resistant coatings to prevent yellowing. Housings are typically made from heavy-duty ABS plastic or die-cast aluminum with proper sealing to prevent moisture intrusion. Many customers report these aftermarket options lasting longer than factory lights, especially in harsh weather conditions or high-vibration applications.
