(LUA) part vehicle condition?

Hi, is there any function (lua) that would check "state / health"? vehicle parts?
I would like to create an additional control light that would show that one of our lamps is broken.

Below is a photo of such an example control light (Ford galaxy mk1)

 

i mean if you damage the engine, the check engine light comes on

 

Adding a "check engine" is not difficult. I mean, if we break the headlamp, it will show a warning light. I need help with the function in lua.
