I ended up using three of the bulbs for the interior too. I opted to not do the license plate light as I want that light to be darker instead of brighter.
4500K will get you the most lumens. Sure the blue at 6700K looks nice, but it is very illegal and I need as much lighting as possible since I drive in the dark a lot.
