Bulb Replacement List

Have a GS on the way, and was looking into backup LED bulbs but I can't find a listing for the '18 Regals that shows what kind of bulbs are used for anything like the back up bulbs. Checked the online manual copy, but couldn't find it there either.

Anyone know what bulb it is or have a link to the replacement bulb list?
