Now a days we already got AC, TV, Refrigerator, Music System and even Bed and Travel urinals in our cars and buses. The only point is these are not the one we could see in our houses.
Let it be a TV or refrigerator or bed, the size of all these are much smaller compared to one we use at home. But they can serve the purpose to an extend too.
Likewise the purpose of chandelier is to provide an attractive look. Go and search for smaller sized chandelier which is built in such a way that which can withstand all kinds of jerks and shakes of the automobile and also which are small enough to fit in the available space.
If you do some google search, you can see the pics of cars fitted with chandelier and most of them are small enough to suit well in the interior.
Whats the purpose of this question, just for a discussion or are you planning to get it done?
