LED bulb for 2018 Silverado 1500 LTZ

[EDL]

My 2018 Silverado has the LED projector headlights.  For the life of me I can't find the OEM bulb for this truck, even on the Genuine GM parts places.  All they show are the halogen and HID bulbs, or the complete LED headlight assembly.  I just want to know what bulb it is (and specifically who makes it).

Anyone know?

There is no "led" bulb replacement. Whole headlamp replacement.

Have you check the ballast?

They are not replaceable because LED'S last for the life of the truck and are soldered to a circuit board. therefore if they "burnout" you have to replace the whole assembly.

Figures.  No, nothing wrong with mine.  My son put aftermarket projector housings on his truck and we're just looking at LED bulbs to put in it.  After watching tons of videos on various tests, they all talk about designs to avoid and which ones work well to avoid dark spots, etc.  Since the ones on my truck work well, thought if they were replaceable bulbs, we'd just go with the same kind.  Oh well.  Will just have do some more research and try some.
