I just fixed my rear center brake light on my 1995 XLT F-150 4x4. All I needed was a phillips head screwdriver and a new bulb. IF anybody needs to know how...

Remove screws and unplug entire fixture. pull off light that needs to be changed (pull off the rubber seal) and take it to your local NAPA or wherever you like to go and get new bulb, then replace bulb and plug fixture back in and screw into truck. You're done! now have somebody look or depress the brake and it will light up.

Hope this is helpful to somebody!
