The rear brake light on your 1989 323 Mazda comes on when you push the brake pedal but all lights are working any suggestions on what the problem is?

Please re-phrase your question; it appears you are saying the brake lights come on when you push the brake pedal and the lights are working (normal operation). If the lights are staying on after you release the pedal, then the problem is with th brake light switch (sticking). Thanks Malcolm
