Why the tail light does not work but the brake light does on the same 3-way bulb?

The marker lights and brake lights run on two different circuits, and usually light up two different filaments on the bulb. If both tail lights are out, either a fuse is blown, a wire is compromised, or both marker light filaments on the bulbs are broken.

My tail light works on both sides but my brake light which is the same bulb is not working on the passenger side. I changed the bulb but the brake light still does not work. What could my problem be.?
You could have a bad wire going to the socket. You can test the connection with a voltmeter. If you are unsure of where to connect the voltmeter try it on the good side first when someone is applying the brakes to see how to connect the meter. Then try the bad side and if you can't get a reading you have a wire or connection problem on the bad side. The taillight bulb has two filaments One is used for the normal tail light and the other filament is used when you step on the brake. When you step on the break both filaments are on at the same time to give the extra brightness. Take the bulb out and check the continuity of both filaments to make sure that they not burned out.
Why would your lower brake lights not work when the upper brake light does work?
By the nature of the question I assume that you are referring to the tail lights and brake lights. My Explorer has four bulbs. Tail, brake turn and backup. They are all in separate compartments of the light assembly. So it could be that you have just burned out one bulb. If you are referring to the upper brake light in the rear window or at the top of the tailgate, same thing. One or more bulbs are burned out. I see people driving all the time with both lower lights burned out and the top working or visa versa.
