Could be many things. First step on these cars is to read the diagnostic codes.

Time for you or a tech to do a parasitic draw test.

Could it have something to do with the new ambient lighting that you installed?

I have a similar issue with my 240, swapped to a brand new battery sep ‘23 and now, mainly when it’s cold, i get a battery discharged warning. Not sure if that’s similar to you, i don’t have any added electrical going on, and the car will start up fine without issues but it is annoying a new battery is doing this to me. While at the same time my f80 has a stock battery, tons of stuff done to it, and sits more than the 240 does (i drag it i don’t drive it on the street really anymore except for a fun pull) and i’ve not had that issue…

Get a fuse drain tester that looks for electrical draw. Pull all the fuses in one box and use the tester on each fuse and you'll see if anything is drawing power with the car off. Then move on to the next fuse box.
