I've just discovered my brake lights don't come on when I have my lights on. They work fine when the lights are off. Confused. Any ideas?
It might help to know that the interior courtesy lights are also not working.
I know nothing about electicals...bad earth perhaps?
I had a cobra immobiliser fitted recently...could something have happened to the wiring when that was done?

IIRC the switch is on the master cylinder behind the dash and mine stopped working too...found the terminal corroded on switch

Interior light not working often means the fuse for the brake lights is blown (my early 'velle) so have you checked the fuses?? wouldnt explain the working/not workig thing witht he lights mind..
