These will help.

Thanks.

Check for blowin fuses.

check the fuses in the fuse panel,if the signal lights are working at the back then the bulbs are good(have seen all tail lights burnt)then you will have to check the brake light switch at the base of the brake pedal.its a 2 wire switch.one wire should have voltage all the time and the other only when the brake is depressed.if the power is not going through the switch then the switch needs replacing.also check for broken wires at the switch also.this should fix the problem.if the third light is not working chances are the bulb needs replacing.

Because the brake and tail(or running lights) are two different circuits. You should find that the stop and turn-signals have their own fuse. Even if the fuse looks okay it may not be. But if you replace the fuse and it still doesn't work try the four-way flasher. If the lights in the rear flash and the brake lights still don't work. Your problem then becomes a power distribution problem. If you know about test lights and troubleshooting this type of problem check for power at the connections for the stop/turn-signal fuse. The power side of the fuse should be the one that has two wires hooked up to it.

keep your dosh in your wallet ,and try this look under the bonnet and near the battery is a fuse box with some really big fuses in like 50 amp and over ,one of these has just burnt out with age or the connections are burnt where it plugs in

I believe this car has a bulb with two fillaments for side and brake lights, it is unlikely that they are both burnt out at the same time but possible. It is more likely that the bulb holder or a ground connection is rusted or loose. The fuse generally covers all rear lights.
