You will be able to sell the headlights in the USA no problem as they are a very sought after item - often described as Aussie Headlights - as in the USA none of them had the bumps on them.
You will need to register on this site and go to the "for sale" thread and take it from there.

Apart from that I don't think you will have many options - was this car wrecked or what??? Why can't it be repaired???
