Thanks for the clarification. My truck is just like yours and I'm liking the look a lot, going to track down these lights asap.

If all working, there might be the control pin on connector didn’t seated properly to communicate with headlight ECU. You can try to re-seat the connectors and make sure that all connected securely. Also, if possible to get the actually DTC code of the error to pin point where is the issues. Test all the functions such as auto on/off, etc. You may also to try disconnect the battery to reset the ECU to clear the code.

i did the ecu reset thru battery power removal and still errror on the dash.
the shop who installed it did not use the wires that came with the new lights. 2 sets of wirings. , did you guys use it to install? or you use the existing wiring ?
i notice the turn signal is not working as well and the auto leveling.

2020 Style Headlights Installed w/Slight Fail
Just joined GX Fam also have a 14 CT. I was able to get myself 2020 style headlights for my 2015. I made the purchase through ebay. Surprisingly they arrived fairly quick considering they came from China.
I installed them as soon as I got them. Everything was great! I love the looks of the 2020 headlights. Everything worked except for the Auto Leveling Function. Keep in mind that these lights are equipped with that feature. I started the GX and noticed that my headlights didn't move up and down. Then I got a message on the cluster "Check Headlight System" and the auto level headlight symbol came up. This bothers me. I have been in contact with the seller and advised me to check all the wiring. Everything physically looks good. I even checked the continuity to majority of the wiring and they were good. I installed the stock headlights back on and no more warning lights.
Now I am considering options:
1. If the seller agrees to a partial refund, Would the dealer or an independent Lexus shop be able to disable or bypass the Auto Leveling Function so the warning message and icon wont come back up?
2. Pay the high shipping cost to return the lights and hope I get a refund and deal with all the BS.
I also got the grill from Ebay. I used plastidip for the surrounding chrome.

There are few components that associated with auto leveling that you can check, the most important, a small motor behind light housing, and control unit at the bottom. The easiest way to diagnose that is to swap the motor with the OEM light. If that worked, you have a defect motor. If that still not working, then there is either you have a defect control unit, or missing something in the controller. You can not swap the control unit since the LED driver is different. You should do this with only one light at time to isolate if just one does not work or both do not not work.
one thing to keep in mind, select your supplier from China is critical, it often happen that some cheaper suppliers making more “look alike” replica rather do for function. I have also seen ones just using defect components from junkyard for the looks only. If your both lights are not working, then you may have fell into one of those suppliers. I will ask for refund for sure.
