Since the problem either lies in the light socket or in the power cable diagnosing the problem requires access to the connections. The most easiest method is using a continuity tester which has two electrodes attached to a digital meter.
Remove brake light interior trim panels. Then you push and twist the socket for the brake light that needs replacing. Then pull out socket. then pull out bulb from socket and place new bulb in the light socket. Once bulb is installed into light socket. Place the socket where you removed it from brake light housing. Push and twist clockwise to lock back in place. Then replace trim panels.
If you want to you could remove the light socket and put in an outlet then plug your light into the outlet.
The screw socket into which an ordinary light bulb is inserted.
I had the same problem. I found a ground contact failure in a rear light bulb socket. If you check this connector your problem will be solved.
Unscrew light from bumper. Turn socket 1/4 turn counterclock. Pull socket out of cover. Pull bulb out of socket.
This sounds like a household light socket you are inquiring about, replace the bulb and socket as well.

To change the third brake light on a ford Five Hundred you first have to open the trunk. To access the bulb for the third brake light look under the housing below the light (from inside the trunk). There is a wire harness that runs into a socket. Twist the socket a quarter turn and the bulb and socket come out. Replace bulb and reinsert socket into the hole the quarter turn the socket to lock it back into place. Done!
No, unless there is an indicator light in the socket.
The rear tail light assembly had problems with the sockets and circuit board. My guess is you will need to replace the socket and circuit board assembly for the passenger side rear tail light.
Check bulb it is a double filament with the smaller being for the brake light Check the socket for power and ground Check the socket for corrosion Could be a problem in the steering column - turn signal not cancelling completely
