  • The mounting bracket is on a rail system (see photo). This allows you to move the light bar up or down by about 6in. You choose where you want the light bar to shine through the grille
  • Only one (1) light bar PRO can be installed
  • No cutting or drilling required. The kit is a complete bolt on using factory openings and hardware
  • WILL NOT interfere with active grille shutters. Our light bars are very slim and the metal bracket is designed to be in front of the shutters.
  • Metal bracket is powder coated black

👌M&R promises fitment of the light bars with the grille as pictured. If you have a different type of grille, please reach out with pictures for confirmation.

M&R doesn't provide a wiring harness. The light bar(s) have over 6ft of wire -- enough to reach your vehicle's AUX switch wiring (if equipped). If your vehicle doesn't have AUX wires, you'll need to source a generic harness separately (available on Amazon/eBay) or build your own.

No AUX wires? Easier option — our Wireless Harness. Powers the lights with no AUX switches and no wires run through the firewall. Clean, simple install.
