Is this the same post as below ?


If the centre brake light is working , switch must be o.k .Check you have the correct bulbs fitted i.e whether single or double contact . Test for power supply at bulbs / holder .

Not sure on that car , reverse light will be single contact .On a lot of cars the brake light is double contact and works tail light also , but dont know on your car . Look at bulb you removed and see if it has two contacts on base .

check contact on buld holder for corrosion or dirty contact. use a multi metter or test lamp and place it onto the connection inside the bulb holder to check if you have power going to it when brake pedal is pressed.
