That’s great info! Thank you for posting!!Yes you can definitely replace the headlight bulb.
The OE bulb is a Philips 16530161 - it's a D1S type bulb rated at 35W - there are a variety of brands such as Osram who make these too, just search for a D1S 35W HID bulb.
The OE ballast is also a Philips part and you can replace these too.
