Just put in the SilverStars in my '00 CSVT. I used 9005s. The way mine was set up was; 9006 for the lows, and 9005s for the highbeams. I took a Dremel to the plastic tabs on the bulbs. They clipped right in, and are working great. They make a HUGE difference despite what anyone tells you. Maybe check to be sure you are replacing the lowbeams not the highs... G/L
