Quick aside, what setting options do you have for regen? Is LOW still an option? Or have they removed that now? Thanks.

New Model Y Tail lights?
- Thread starter ModalYYJ
- Start date
I have a July build (28xxx) and have the 4 wire connectors. I installed the updated taillights, and they’re only half working.
- Amber turn signal works
- When brake: both C and amber light up
Swapping the old taillights on today. What do you guys think the issue is?

You would need to have the car's configuration updated to know it has the new lights installed.
From the picture, it looks like the harness can be plugged in two different ways? Did you try flipping it?
I still have 2 options - "Low" and "Standard". Not sure what cars are affected by any changes. I have 2020 MY LR running software build 2020.44. July build VIN 29XXX.
Thx. Trying to understand how this will be applied, no definitive line in the sand yet.
If they will do it for you. They might be able to do it remotely, I just don't know if they are willing. (They tend not to, like they wouldn't enable the new digital tuner that people installed in the MCU2 upgraded vehicles.)
I just got off the phone with Burlingame, CA Service Center. I explained the situation and he recommended I "submit through the app-- a tech advisor will reach out and can likely do it over air."
I hope hope this is the case. I'll keep you guys updated
Apparently true — see directly below.
Mobile service booked through Burlingame installed my lights. UPDATED: You're right! Yellow on braking but they do blink as turn signals. Will reach out too.
VIN 32xxx, Late July build. I have Low and Standard, this article says that Low is gone only for cars that never had it -- starting with June builds: Tesla mysteriously removes regenerative braking strength option in new cars - Electrek
They only go in one way, but the bottom and top are switched (rotate connector 180 degrees) between the old lights and the new lights. It should be plug-and-play like it was on mine -- except for the amber lights coming on when braking. See above.

Mobile tech made a visit yesterday and said that there is no taillight configuration that he could see but reloaded my firmware. No change -- the amber lights still illuminate with the outer C but they also blink like turn signals. Doesn't bother me at all.
Same. I just chatted with a Diagnostic Technician from Burlingame. Confirmed: If you have the 4 connectors AND your MY was built before mid August, currently there is no configuration change available that will allow the new taillights to function properly. According to the tech, this issue is fairly fresh so it's going to take some time to find a resolve-- if any. Based on the conversation I feel optimistic about it, so we'll see.

That gives me some up that this can work without a harness change and/or hack. Technically I can't see why it shouldn't be able to work as essentially you are running the old cars in euro tail light mode unless there's something I'm missing.
Did we ever figure out the purpose of the additional wire in the newer models?
The additional wire is to separate the brake and turn signal lights.
I don't think that a car without the extra wire would ever light the amber portion of the lights.
Right. Not unless some electronics genius comes up with a module that can detect feeds from braking vs. turn signal (then split it into two outgoing wires for the new lights) which are currently fed through the same wire that lights up the LED bar. Seems doable but way above my pay grade.
