hey man, not sure if your still interested in this... i replaced all of mine with blue led lights, i have a pic if you want to see it done. i not only replaced the lighting with blue but EVERY indicator in the cluster with blue. no no matter what lights up its all blue haha. i can tell you that the bulbs DO come out, i had to take a safety pin and kinda pry and pop them out..they just pull out. if yours DONT, they do have on Super Bright LEDs ? LED Lights, Bulbs, and Accessories
some ones you can order that will fit your jeep. they have the twist on kind that you can order any color pretty much you want. the ONLY other thing i'll tell you is that if you are just wanting to do the lighting behind the needles, then all you do is replace the bulbs with leds. if you want any of the other ones like i did, you have to remove the film between the black panel and the light socket, its NOT hard at ALL! took me like 5 min, but i took my time so i didnt crack anything. I can show you how to do all of this if you are still interested. let me know man i really like the blue look and it turns out looking really good!
