2025 Rear driver side night time driving light fail

[SoySauceSoakedSaltine]

Hey y'all, so my rear driver side night time driving light failed at approximately 1300ish miles on October 5th. The indicators work and brake lights work just not the night time driving light. I got no message on the cluster that a tail light fault was detected and I've attempted to reset the BCM by disconnecting the battery and have it sit overnight. The only thing I hadn't done was touch the +/- ends together to discharge. Big Blue opened a warranty case and the part ( RB5Z13405B ) is on backorder until November. So my question to you all is, What other techniques would y'all suggest to remedy this? Also what are the differences between these two parts ( RB5Z13405A ) and ( RB5Z13405B ). Both listed on Fords parts page say they are the driver side taillight assembly but the A variant is a few buck more than the B variant. The B variant is what the dealership has on order but they say its on backorder, online does not say that but the A variant is showing on backorder.

Any help would be greatly appreciated. Just like any one would, I'm getting quite impatient since I have not been doing any night time driving and would like to get my build project rolling.
