You may need to have the dealer program the lights.

what is the correct part number of the GSF headlights ballast ?

 

For what market car?

 

USA market

 

There is no "ballast" for the headlights. There is a computer subassembly (with left - 81056-30L20 - and right - 81016-30L20 - versions) attached to the headlight housing, but there isn't a ballast like you would find with HID bulbs.

 

lobuxracer, am planning to upgrade my 2018 GS350 f sport to triple beam headlight. Would you know if this is just plug & play providing I purchase headlights & headlights controller? I’ve been reading triple beam headlights threads on the mod on 2017-2020 but could find any info. Most triple beam mods are 2015 or older GS.

 

No idea. I've never looked at the other GS models wiring to see if this is possible.

 

Did u make the conversion?

 

I think Techstream will solve your issue.
You'll need Techstream to initialize the ECUs and to sync their data to the car.
