There are so many threads on interior LED swaps with so many variations, here's my low budget practical solution with great results. All were ordered through Amazon, I am a PRIME member so I got free 2 day shipping - Total $26.00 invested.....YMMV
The results were great, intensity/color was consistent across all bulbs. There is a slight white/blueish tint, but exactly what I would expect from a "white" LED. When replacing all bulbs, remember these bulbs do have a correct polarity to them. So if you install a bulb and it does not light, remove it, flip 180° and reinstall. Check this by plugging in each assembly BEFORE complete reassemby and then finding out you have a bulb that won't light.
- Front Map lights were very easy to remove and replace pulling from the rear of the entire assembly.
- 2nd row map/dome assembly can be removed by carefully pulling down from each side of the lens. When installing the 42mm Festoon bulbs, first remove the incandescent bulbs, squeeze the 2 prongs of both sides of the bulb holder together and these bulbs will not be loose as some folks have experienced.
- License Plate are quite easy, there is a small tab you push in on the lens and the assembly pops right out
