1999 saab "brake lights" - 1999 Saab 9-5

no

both attached to the fire wall drivers side

clutch master replacement
brake master replacement

ESP control unit fault or pressure regulator switch

LCD failed. very common on Saab new unit required.

has to be your brake light switch unusual though normally wired to ignition circuit but saabs normally have side lights wired to come on when ignition is turned on due to swedish laws
try brake light switch at foot pedal or maybe on master cylinder just remove a wire one side of switch if they go out you have your problem

i know this may sound strange but remove the brake fluid cap. on the cap is a sensor, do this away from any other vehicle and yours and shack the sensor by the cap a good few times. as fast as you can. then re fit the sensor see if the lights go off. sometimes it works sometimes not. this just because the brake light is on, this only usually comes on when the sensor thinks there is low brake fluid. and it can also tell the abs as well. and this is why both the lights are on. also make sure the fluid is at full markings.

try the bulbs, then fuse, then the brake switch on the pedal

You will need to remove the interior panel on the hatchback door to access the light.

You have a blown head gasket.
