2016 CD - What is the OEM bulb part number for the low beam bulb and how do I change the bulb?

I was wondering is the low beam headlight bulb covered by any CPO warranties? I looked in the manual and it recommends having this bulb changed at the dealership and haven't found any instructions to change it on my own. The passenger side has a pinkish hue to it and I'm assuming that means the bulb has gone bad and about to go out. Is this a DIY repair? Attached are a few pictures of the light from the bulbs.






This shows the pink color best



Edit:

Completed the replacement
-removed the headlight as detailed in the owner manual
-unscrewed the five screws using the tool included with the car near the spare tire as recommended
- twisted old bulb out
- disconnected old bulb
- removed green “harness” from old bulb and installed on new
-reassembled and placed headlight back on as per the manual

it was simple and I would categorize as easy on the diy scale, only tricky part was putting the whole headlight back in, I thought I had to twist using the headlight tool into the locking position and it just was working but after a bit of wiggling it actually clicks back in place which is good to know.

Also so the bulb ran pink for about a week of daily using before going out completely.
