I highly recommend these bulbs for the interior lights. (Note: these are 921 replacements. If you currently have something else, they won't work for you.)
We just replaced all of our bulbs in our Cherokee Grey Wolf 17BH with these. They were significantly cheaper than others I had used in the past, and the color and brightness matched the old bulbs almost exactly. I just made the change, so I can't comment on the long-term durability at this point.
