Rear turn signal in taillight?

His previous post seems to state that the sequential circuit is in the taillight:
"Due to new cars having a CAN system(Controller Area Network) almost every component has a "computer" or more specifically, some sort of electronic circuitry that can communicate with the body computer. In the RCL and BUL these "computers" will report any outage issues as well as a current on vs off function for the lamp.With that being said, what determines how the lamp lights up is the computer that is INSIDE the lamp. So unless you swap out said computer and design you own computer (which is impossible without destroying your lamp) you will not get sequential turn signals."
What I wonder is, can I "plug and play" the lights from japan and then the computer in the new light can communicate with the ECU of the car automatically?

Sorry for the double post, But the automotive industry calls the lamp that contains the Back Up function a BUL regardless of what other functions it contains.

Just to confirm, am I right about the difference between BUL and RCL in the pic?

Also, so then you mean I can buy the BUL from e.g. japan and plug and play?

Thanks so much for the info!
Next challenge: sourcing the 740 BUL!

Go to japan, Find a Lexus Dealer, buy lamps, ship back home. Or wait a few years for "JDM" parts on Ebay.
