They are VERY easy to change. I read alot of reviews on LEDs and apparently not all are equal. I read some bad things about autolumination and verybrightleds. I read good things about
www.v-leds.com I got all of mine from there. I replaced every single inside light with white leds from them.
It didnt take me long at all. The only ones that are a PITA are the little wdge bulb in the headlights.
The front and back dome lights come right down. I just use my fingers to pull them down, but if you have big fingers you will need a flat screwdriver and a thick towel. You have to pull really hard at first and it makes a loud POP, but it is just the METAL clips popping out.
I had tried some LEDs from Pep Boys that were crap and not bright at all, so I have taken mine down 3 times and all of the clips are still 100% perfect.
The ones in the bottom of the doors are on a plastic piece that you just pop out with a flat screw driver. Same with the trunk. The lights by the driver and passengers feet you have to take 3 philips screws out then the panel comes down.
for the bottom of the door lights I used right angle leds that are all on one side facing down because thats how the bulb sits.
All of the interior lights are SUPER BRIGHT now.
