Fits the bill
Half the cost of everywhere else AND DOT/SAE certified! Be forewarned, do not buy a cheap "imposter", you know, ones without the DOT/SAE markings! They wont pass a state motor vehicle inspection!

High Mount Third Brake Light
Web site was very easy to navigate through. Explanation of part was better than I got from Ford garage. Easy to pay for. Confirmation of purchase and shipping updates were punctual. Product fit and worked as intended.

Fits Perfectly
My original third brake light cover cracked on my 2010 Ford Explorer Sport Trac which caused water leaks inside my vehicle. I ordered this replacement and it fits and works perfectly and looks great. Thoroughly satisfied. Thanks.

how do you install 2006 Ford F150 Truck High Mount Third Brake Light?
Joey S August 11, 2015
Screws on the brake light but youll need to remove the two coat hanger clips inside the vehicle. The headliner needs to drop some to gain access to the wiring harness clip. Not difficult and suggest looking for a YouTube video on how to remove the headliner clips since that part is not straightforward.

I removed the two screws, then turned/unlocked the light sockets and removed. Then I replaced the bubs with the new ones that came with this light and locked the old sockets in place in the new light, put it in place, put in the two screws and done! Super easy. The only tool thats needed is a phillips screwdriver.
