3rd brake light
Do you know of any company that offers a 3rd brake light with F150 or FORD in the lens that lights up when you mash the brake or park lights are on?
The third brake light should only come on when you step on the brake pedal. Many Fords have clear cargo lights on each end of the third brake light assembly that will come on when a door is open or when you turn on the switch on the dashboard. Try Rockauto.com or your local auto parts store for a replacement. Hope that helps! Jim
Whatever you get, make sure it comes with a good gasket and is seated properly before you attached the light to the truck. If the gasket leaks, you'll have a hell of a time cleaning the headliner if rainwater gets it et.
