Tail lights quick FLASH when unlocking, opening and closing any door (!!)

I have installed a pair of LED tail lights, and they do NOT hyperflash. However, when I unlock, open or close any door, the rear right light flashes for half a second (only the rear right). Super weird. Kinda looks like the car is letting go of some electricity through the light, or even static (why would it flash when closing a door ?). I tried another brand of LED tail lights and they do the same. I tried to reground from directly the light harness, still happens. I tried different resistors, still happens.

Anyone has an idea of why this is happening ? Thanks ! I am slightly going insane.

do you have a programmer that allows the change to LED lighting? if not, you need a resistor.

Depending on where you bought the LEDs, reach out to the vendor and see if they will send you the resistors; I've run into this and the vendor sent out the proper resistor free of charge.

You mean you ran into the same issue (quick flash when closing or opening a door) ? And a resistor fixed it ?

I did reach out, they made me pay for resistors, I installed and still did the same thing. So I doubt they know what type I need.

Which resistors helped you ?

Are your backup lights working properly?

I'd also check the wiring to make sure it isn't nicked or making ground contact where it shouldn't be.
