Brake/rear Lights

[di.paul]

when side lights are on and the brake pedal applied o/s brake and sidelight go off. Any ideas?

I do not know what car it is but things like this can be the result of a bad earth connection or corrosion in the light bulb holder or wiring connector. A faulty bulb could also give problems. So I would check the o/s rear light and its earth connection. You might also have problems if you put the hazards on whilst other lights are on and they may flash a bit as well as the indicator.
