About this build

Dakota S. gave a classic 1986 Mercury Marquis a modern touch with blue rock light underglow. The build runs the Blue Rock Light – Single under the body, so the glow under the Marquis is a solid, consistent blue that suits the car's long, low profile and classic chrome.

Rock lights are not just for lifted trucks. On a long, low classic like the Marquis, light under the body pulls attention to the body lines and stance and makes the car stand out at night meets and cruise-ins. Want this look on your own classic? Every part on this build is in the parts list above, and our team can help you work out how many lights your car needs at 1-833-325-3250.

Mercury Marquis lighting FAQ

Can you put rock lights on a car?

Yes. Rock lights work as underglow on cars too, like this Mercury Marquis running blue rock lights under the body.

How many rock lights do I need for underglow?

As a guide, 4-8 rock lights cover the wheel wells on most trucks and 12-16 give a full underbody glow. Call 1-833-325-3250 to match a count to your car.

Is there a warranty on FCKLightBars lighting?

Yes. Everything FCKLightBars sells carries a lifetime warranty.

How it’s installed

  • Mount the blue rock lights under the body, spacing them along the rocker panels and near the wheel wells for an even glow.
  • Route wiring along the frame or body seams, away from the exhaust and suspension.
  • Keep every connection sealed against water and road grime.
  • Call 1-833-325-3250 if you need help planning a light count for your car.
