I got the 194-WWHP5-PC from Superbrite LED which is basically the same 194 bulb plus a twist socket adapter. It turned out I didn't need the adapters but I heard that some similar year instrument clusters need them (I didn't want to take my panel apart twice). I only changed out the 5 general illumination bulbs in my moonie cluster but the turn signals and idiot lights are stock incandescent. Since I keep the interior illumination about half-dim, the LEDs don't overpower the other indicators.Got a reply back from Superbright LED. They recommended using this bulb in my instrument cluster.
