Lights on warning buzzer

[countryman]

Hello all.

I recently noticed the buzzer, warning that the driver has left the lights on has stopped working.

I have checked the switch on the door which operates the interior light and that all seems fine and also checked if the handbrake warning works and this also still beeps, is it the same buzzer as the lights on warning?

Anyone have any other ideas to find the fault?

Thanks in advance.
