Vehicle (car) lights - exhaust smoke

I did searching in forum and docs, but not find the answer.

1. If my model have the lights nodes, how script them to working ?
2. If i want that my car have exahust smoke, i can use the jetnozzle node?, how script them?

if someone have a full script example using all possible vehicle nodes, i apreciate it, thanks. (And will be useful for the TDN...)
