I understand the dash seatbelt warning light is part of a buzzer/light system. I want to make the light go but not the buzzer.
The circuit has a bi-metallic switch which, if working correctly, must disconnect the circuit when it heats up. I am trying to build an electronic version which will leave the light on for around 20-30secs when the key is turned on.
This may not work but it is worth a go for authenticity.
