My right hand indicator is fine until i put my foot on th ebrake or have the headlamps on, then the brake light starts to flash and the indicator goes very dull. All lamps around the car appear to be working.
YOU HAVE A EARTH PROBLEM IF THERE IS A PLUG ON THE REAR LIGHTS TRY TO CLEAN IT WITH SOME SAND PAPER OR LOOK BEHIND THE CARPETS UNDER THE REAR KIGHTS AND LOOK FOR A BOLT OR SCREW WITH SOME WIRES CONNECTED TO IT REMOVE AND CLEAN
