Yes it does fade in and out like factory. When they are the dimmest, they are about as bright as the factory light, and a couple levels better is about as bright as other LED conversion kits, and then it gets bright!

I probably wont do a write up on it, if I did it again, i'd get some other lights. These are a little too big, so I had to do a little more modifying than I intended. The length of these is great, but a little too wide.
To get these to fit, I had to modify the switch, the switch panel, the clear cover, and the light housing. A little much.
These measure 50 x 40mm [2 x 1.6"], so 50 x 30ish would be better.

Depending on the LED panel size, it will require different modifications.

Basically all you do is take the light apart, and figure out how to mount them. I used the double sided tape that came with them, and then glued them in place. I had to put a couple broken off pieces of the reflector (since its no longer used) in there to hold them up to just the right angle. They are angled slightly outward, and rearward, to aim at each front seat, as you can see in the pic below.

Most of these panel type LED lights come with different socket adapters.
Since our cars, for some odd reason, only came with one bulb, it will require you to splice the two LED panel wires together. As in the picture below. However, those quick connect splicers did not work well, so I ended up soldering the wires together.
