my '11 jkuu does this.
I will hazard-a-guess that it has something to do w/ the fact (confusing as heck, btw...) that the Jeep JK/JKUs have independent Right/Left circuits for the tail-lights ( as opposed to the combines taillight circuit on most vehicles) & that shutting the door temporarily ( for a flash) disables the interior dome lights and dash indicator during the slam, enough-so-that the right circuit gets a surge of juice just enough to "flash" the pulse-width-modulated load to the rear right tailight , over the CANBus ....Now,note that I may have the reason for it happening wrong & that deduction has the potential to UTTERLY be the dumbest thing I have ever spewed forth from my pie-hole but , you are not crazy. My stock tails may have done it - i never noticed- but I have run LEDs early from ownership ; i could tell the stock boxes were a vulnerable part and gonna get broken off by me - I ripped those off on trees and the rear right always flashes even with resistors on the LED replacement tails that I run . I replaced the load resistors in the circuit to make sure they weren't the cause.
it flashes like that.
