I can confirm this, the previous owner of my C30 replaced all those bulbs for LED.
I definitely like the white light, much more modern. I had to replace one in the footwell and bought replacements from eBay, went for the CAN bus OK versions and haven't had an issue.
One thing to be careful about, measure the bulbs that come out and ensure the LED replacements fit in the bulb available space... The first replacements that I bought were too long to fit in. Schoolboy error!
