Volvo VNL Gen I Driving Lights

Frequently Asked Questions About Volvo VNL Gen I Driving Lights

Will these driving lights fit my Volvo VNL, and how do I know if I have the Gen I body style?

Volvo VNL trucks have gone through several body redesigns over the years, commonly referred to as Gen I, Gen II, and Gen III. The Gen I body style refers to the earlier VNL design, generally produced before Volvo's major exterior updates. The mounting locations, bumper shape, and fascia openings differ between generations, so a light designed for Gen I will not bolt up correctly on later models. If you are unsure which generation your truck is, check the shape of the bumper and grille area, or contact us with your VIN or model year so we can confirm fit before you order.

Are these driving lights DOT and FMVSS legal for on-road use?

Most auxiliary driving lights sold for Class 8 trucks are designed to supplement your factory lighting and are not intended to replace or interfere with required headlights, turn signals, or DOT-mandated lighting. Legal use often depends on how and where the lights are wired and aimed, as well as state and local regulations regarding auxiliary lighting. We recommend reviewing your specific product listing for any DOT or SAE compliance markings and checking local regulations before installation, especially if the lights will be used on public roads.

What is the difference between LED and halogen driving lights in this category, and which one should I choose?

LED driving lights typically offer longer service life, lower power draw, and a brighter, whiter light output compared to halogen options. Halogen lights are generally more affordable upfront but tend to burn out faster and draw more current. If you are running additional electronics or want to minimize maintenance down the road, LED is usually the better long-term choice, though halogen remains a budget-friendly option for drivers who prioritize upfront cost.

Do these driving lights include the wiring harness and mounting hardware needed for installation?

This varies by product, so it is important to check the specific listing before you buy. Some driving light kits include a complete wiring harness, relay, and mounting brackets, while others are sold as the light unit only and require you to source or reuse existing wiring and hardware. If a listing does not clearly state what is included, feel free to reach out to our team and we can confirm exactly what comes in the box.

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

Many drivers and owner-operators install auxiliary driving lights themselves, especially if the kit includes a plug-and-play harness that ties into existing connectors. Basic installation typically involves removing the bumper or fascia panel, mounting the light, and connecting the wiring to a switched power source. If your kit requires splicing into the truck's electrical system or you are not comfortable working with 12-volt or 24-volt wiring, having a qualified technician handle the install is a safer option to avoid electrical issues or blown fuses.
