One more item. When replacing the bulbs / switch pack -- disconnect the battery. (It's probably not a bad idea to disconnect the battery any time you touch the electrical system of a Jag.) After replacing mine, the lights in the switch pack wouldn't work, nor would many of the interior lights (clock, overhead console, etc.). I came to think it was the Dimmer Module as the gauges would light but not when the headlights were on and none of the other small locator lights functioned. Not quite how things should work. Somehow when doing this work, I blew Dimmer Module fuse number 3 (5A) in the LH under rear seat fuse box.

 

My own previous post but I can't figure out which ones I need as my fan,valet,unlock & temp up & down(marked w/ red X) should all be the same color yet I see green,blue & clear listed as console button bulbs lol ?!

 

How about someone shares the bulb numbers is it a secret?
