It will work great for the instrument panel, in fact I use LEDs too. They were already plug-n-play for the light socket with the resistor built in.
However, it will not work for the center console, dome lights or tail lights.

The key is the viewing Angle: 40±5degree. In other words it lights up only in front of it. The spider takes light from around the side of the bulb, the dome lights would become spotlights and the tail lights would need well over 30 to produce enough light to be seen by other drivers (Even those would just be dots since the reflectors are not made for LEDs and will not spread out their light).
