2015 Toyota Tundra TRD LED Light Bar Installation

Posted by Mark Dimayacyac on 12th Sep 2017

"Hi everyone, my name is Mark Dimayacyac and I am the owner of a 2015 Toyota Tundra TRD. I had an opportunity to install a  RAZIR LED Light Bar from HIDextra and this is my installation blog for everyone. Check out the video and instructions below. This was a straight forward install after you know where you want to place the bar. I kept it simple and had it behind the grill and on the factory front cross bar. You will need to make drill holes to tighten the light bar down. I do recommend buying the harness LED switch as it makes the installation a plug and play install. Let us know if you have any questions".

Before getting started, I would like to take this time to let everyone know there are other locations where you can place the light bar. You can place it above the windshield by the roofline but you will need custom brackets, I wanted to stay discreet so I placed it behind the front grill of the bumper. This will be a personal preference for everyone.

  • ¾ Small Extension

  7. Using the tape measure extend it from end to end on the upper support.
  8. Place the LED bar on the upper support and find where you would want/prefer to mount/center your LED bar. (Try to push the bar as far back away from the grille).
  9. Now mark the holes where you choose to drill.
