How to change right brake light bulb - 2002 Lincoln LS

Your right brake light is not the same bulb as your rear running light that comes on with the headlights. Different bulbs. Your right brake light is simply burnt out or has worked its way out of the connection. Take it to Advance Auto Parts. They may even change it for you. Not a big problem.

Fast flashing dash signals mean there is a bulb issue-DEFINATELY!

If both are not working that is a sign that you have some other problem and not burned out filament's in the bulbs bulbs. Try turning on the four way flashers and then off again a few times do the rear lights flash? if so the bulbs are ok. If the brake light still don't work check the bulb socket with a DC volt meter while the rake lights are help on by a helper, if you have voltage then likely the bulbs are the problem. If you still think the bulbs are the problem the way to change them is outlined in the owners manual with diagram's which I do not have.

Chek the light harness ground connection, for each "faulty" bulb. l suspect the brake lights are detecting the gound from the running lights, which is the only time they all function.

There is a shortage some where at the brake bulb and low beam holder. Take off the bulbs and inspect carefully those losing wires attached to the ends can cause the problem. Good luck.

Check your brake light fuse, also make sure you installed the bulb in the right way, if not in the right way will blow a fuse and will also not let you shift gear's due to blown fuse.

the problem is with the bulb, what is happening is when you push your brake pedal with the lights off you are turning on you parking light side of you bulb, when the lights are on the parking light is already lit up so when you push the pedal you see no change. try a new bulb

on either side of the boot interior, there are what look like air vents. these clip out from the top (with a flat screwdriver) you then unbolt the light unit, pull it out. the bulb holder then unclips easily.

Have someone apply brakes. Observe which bulb lights in the left light housing. This is the bulb you want to replace.

make sure u have put the right bulbs in. rear brake lamps are dual filament....
