If you don't think they are whiter and brighter, you can package them up and Wal-Mart will always take them back or let me know and I'll buy them from you. I can always use a space couple of bulbs.
Warning: those Sylvania's are so much brighter than the OEM bulbs that if you have the fog lights on at the same time as these lights, it makes the fog lights look dim and yellowish. After I put them on, I went back to Wal-Mart and bought Slyvania's for the fog lights.
