If you are purchasing bulbs for the interior of your maxima, I just went through some hellacious research, so now you don't have too. I am converting the courtesy/dome lights on the interior of my max to green. Most of the bulbs for it are size 194(courtesy, sidemarkerk, trunk, etc. However the dome light is tricky. I have seen other threads stating its a DE3175. This is correct, however there are multiple sized bulbs with this code. They come in different lengths: 31mm, 36mm, and 39mm. Some websites distinguish this, but most don't. I measured mine and found out it's a 31mm. It's probably a good to measure the one in your car so you don't order the wrong length. The mounting points in the dome light for the bulb are flexible, however I'm not sure if a larger size would fit correctly. Don't make the mistake I almost did and order the wrong size.

Sorry for being long winded, but I wanted to give details so no one gets confused.

I'll be placing a pic on my car once the stupid gold wheels that are on it are replaced(on there when I got the car)
