There are certain parts on your car, like Acura headlights, that may need to be replaced from time to time. New ones can be a little expensive; however, salvage parts are very cheap but also in great condition. Your headlights should last for years, but bad wiring, an auto accident, or other problems can cause you to replace it sooner than expected. In that case you do not want to buy a new one because it will be expensive. Instead you want to buy it from a junk yard where you can also find other Acura used parts that are in great condition but sold for little money.
