Default Bulb out indicator

This is a strange one. It only comes on when I apply the brakes. If a bulb was out the indicator would stay lit. It goes off when I let off the brake. Anyone else have this happen? Every bulb works and they all are the right bulbs.

I have that and it's related to the hand brake - when the hand brake is engaged the light comes on when I push the brake. As my handbrake light was disconnected by a PO and the handbrake is inop it is the only sign I have when the car believes the handbrake is on. Handy for me as I have a vert and the car requires me to have it 'on' before I can operate the top mechanism.

Exactly.

This is how the system check the brake lamp bulbs.

Either the handbrake is applied or the system "thinks" it is applied due to a sticky/misadjusted/faulty handbrake switch

Bingo! My handbrake is not working, so I disconnected the leads. Its a bit## to get at without removing the seat. Thank you again.

That's why mine is still the way it is. I'll get around to fixing it sometime For now the top works and I know when the brake lights are working
