I went to walmart first, it said on the website that they had some, but I couldn't find any in store. So I'd look online there first and call n see if they carry them.
then I went to a computer store, it's called microcenter, they aren't everywhere tho. So maybe check locations for one near ya. It was only 15 bucks and they had cheaper ones too. But that's about the average price I found was 15-20. N you'll also need a 4 pin moles extension or y cable. And then a headlight pigtail to be able to plug the ballasts in like you would into the car. I just cut up an old hid relay for that..
