Playing sound for turning engine on/off would be no problem, however lights has nothing to do with sound. Anyways when this is done you will be able to choose yourself what sounds will be played and for which player on any game event. The plugin will provide natives that you control this with through pawno, something like

PlaySoundForPlayer(playerid,soundid,volume);

Remember all sounds/music you will create yourself in a sound pack which then is downloaded by your users, its also in this soundpack you specify what soundid belongs to what sound.
