I actually did this before I joined the forum. The last couple of cars that I had I put LEDs in all of the interior lights. I was surprised at how many lights the Sienna has. Luckily I had enough on hand to replace all of them.
Every internal light except for the front doors and back cargo were 168/194 bulbs. I replaced them with a single LEDs which is not very bright on it's own but if you add them together it does make quite a difference. I did not take a before picture as I did this during the day. I also added LEDs to the license plate lights.
The rear cargo light is a 3022 bulb which I had 24 LED panels for from other cars. You can see that in the second picture. The only bulbs I did not change is the bottom front door bulbs. They are also 3022 but I am not sure if I want to put the 24 LED panels in the bottom doors, it might be too much. I think I will just look for 3022 single LEDs to finish the job.
