The gauge cluster lights are very easy.. Pull the dash trim off then 4 screws to loosen the gauge cluster. I didn't even unplug it, just felt around behind it and there are 4 bulbs back there. Just a quarter turn and they come out. Standard 194 bulbs with a green sock over the tip. I believe you can even remove that sockand put it on your new bulb. I replaced mine with white leds. Gives a much cleaner look
