Frequently Bought Together

This kit is designed to replace dim/failing headlamps on second-generation (2004+) Volvo VNL, VT, and VNX series trucks. Here’s what’s new in version 4.0:

  • A large glass lens, mounted in a more compact metal holder,
  • New ballast design,
  • Cast and curved high beam shutter with more powerful solenoid actuator,
  • 100% American-made Delphi wiring harness with easy-to-read labels,
  • Twist-lock bulb retainer–no more spring and nut,
  • Improved bracket design, with more compact external dimensions to make installation easier, and
  • Improved optics for even better light output!


What about other kits out there that don’t cost nearly as much?

This is the first and only kit to provide a high-quality easy-to-install headlamp system designed to meet FMVSS 108’s performance requirements. Click here to check out a video review/installation demo.

The kit replaces the low beam projectors as an assembly, and the kit is removed and replaced through the bulb access covers on the back side of the headlamp housing. No baking, cutting, drilling, or gluing! The benefit here is that for some reason you’re not happy with the kit, it’s just as easy to undo and go back to stock, and since we’re not putting any new holes in the headlamp assembly you’re not at risk of any leaks where dust or water might enter.

Many HID retrofit kits use generic components, matching only a bulb base. Others include wiring harnesses that just adapt from one bulb type to another. Included ballasts are often of poor quality, and have trouble starting quickly, restarting hot bulbs, or have slight flickers that can be bothersome. They’re the type of kits that NHTSA has ruled can’t be made to meet the performance requirements in FMVSS Standard 108. This kit is different.

No Fault Codes, No Programming Required

You may also know that these Volvo trucks have a lighting control module (LCM), which detects faults in the lighting circuit. In the event a failed bulb is detected, a message appears on the Driver Information Display, and the LCM stores a fault in its history. If the LCM detects a load that is too high, the LCM shuts off power to that circuit. This kit, specific for these trucks, is designed with this system in mind. When this kit is installed according to the included instructions, you won’t see any error messages for the lighting system–whether you’re using the low beams, high beams, or flash-to-pass functions. The kit doesn’t attempt to defeat the LCM though. If you should have bulb or ballast failure, the LCM will still be able to let you know. No trip to the dealer, and no programming changes.

What’s wrong with the lights that came on the truck?

The OEM Volvo lights are prone to weathering, going from a clear outer cover to a milky yellow with age and exposure. This problem is visibly apparent from outside of a truck. More importantly, and hidden from view, is the deterioration of the reflector surface that significantly reduces the light output from the low beam projectors. And with only 18AWG wire to the lights, in most cases you’ll only see about 10.5V at the stock bulb–resulting in brightness 33% lower than under test conditions. Stack up a dim bulb, pitted projector, and a hazy, oxidized lens, and it’s no wonder it can be difficult to see at night.

    The difference is night and day! I bought this kit in August and have run it for 5 months now. It is amazing how much better it is than the lousy OEM Volvo lights. I’ve seen online where a few people have upgraded bulbs only or tried to make the factory lights better. Why bother? This kit is absolutely worth the price. Quality components used and phone support was great. I had a small issue because I flip-flopped two wires and thought I had a bad bulb, it was my fault though.
    Great improvement.
