I have NO idea if I am in the right place but I just have a question. My husband has an 06 Mustang Gt and wants blue headlights. I would like to get them for him for Christmas. I have learned I need H 13 but that's all I know. I went on ebay to look around and all I found were bulbs...will this work? Can he just pop out the current bulbs and put the new ones in as long as they are the H13 as well? Any help is MUCH appreciated! Thanks
