I tried to search but came unsuccessful to find out what the bulb sizes are.

I want to know the bulb size for the license plate lights, as I want to replace them with white LEDs.
Same with the interior lights (example the map lights and the lights that turn on when you open the doors) Led sizes would be great help… Thank you.

 

look in 'lighjting'' section. there is a complete list. there are no conversions for size to led.

 

a few of us have done this. i think mine was posted in the "Modded G37 post pics HERE" thread. just check around, you'll find em.
