Need some help i have 2005 f150 and today the brake lights are not working all the time. if you push the brakes hard they come on the they go off. pump them a few times the lights come on. hit it again then on lights

The first thing to check is the brake senor switch that is right behind the brake padel. The switch known to be sticky or the micro switch is bad. Easy way to check is to crawl under the driver side and push the switch by hand. If the switch "clicks" or bounce back freely, check to see if the brake lights work the same time. The switch is not expensive and easy to replace.
Hope this help.

 

Thank you for the input i changed out the part very easy five minutes and that was the problem. It also fixed my cruse control that would work on and off.
