Hey guys. I recently purchased an is350 from copart and done fixed it up except for one thing
I have a "Check Headlight System" on the dash
Now I was able to have a lexus dealership tell me what it meant, to my surprise they said I have the wrong style headlamps on
RN I'm currently running HID lamp instead of LED. The mechanic shop I used said LED didn't fit (which I ordered 1st)...........but HID would (what I'm running now)
Im also seeing conflicting stuff when I run the VIN on lexus website themselves... to look up the specs
Depending on region and package will depend on what headlights you get.
According to your screenshots it's supposed to have LED headlights.
The physical headlights are the same between HID and LED...the difference visually is the amount of projector lenses.
The HID has a single projector while the LED has dual projectors.
If you have the single HID projector headlights in the vehicle now that would explain the warning message on the dash.
Get the proper headlights...plug them in...and you're good to go.

Your best bet to validate this is to provide your VIN to a Lexus Parts counter and have them look up what fits your car. The online resources are showing either the HID or the LED "fits" using your VIN which clearly can't be right. The only other way to be sure is to check the wiring harness that plugs into the headlamp unit. The LED and the HID have different part numbers, and they usually have a marking on them to show what the part number is. My bet is, it's not possible to plug the HID unit in with the LED unit harness and vice versa.
Gotcha. Now last piece to the puzzle, I grabbed the harness from the chassis. Do these connectors look right? I remember seeing somewhere that a 8 pin connector is for HID and a 7 pin connector is for LED
Maybe this will help. I can't verify the LED lighting connectors, but these are the details for the connectors in your hand. The 8 pin is for the main light. The 6 pin is for front turn signal and auto-leveling motor. The 3 pin is for the clearance lighting. The 2 pin is for the fog lights. Here are the wire colors for the 8 pin and 6 pin. With any good luck you'll have a clearer picture of what you have.

To clarify one thing...the HID and LED headlights have the same 8 pin connector. The difference is the HID headlight uses 6 wires of the 8, and the LED headlights use 7 wires of the 8.
In your pic, the bottom left connector is the headlight connector...8 pin. Regardless of the headlight the vehicle actually takes, pin 2 is always empty.
Of the remaining wires, pin 7 (light green for drivers side and black for passenger side) is the additional wire that the LED headlights need.
If the connector is missing a wire in pin 7, then your vehicle uses HID headlights. If there is a wire in pin 7, then it could mean one of two things...the car needs LED headlights, or, the car is pre-wired for LED headlights, which is absolutely possible since it's a 2014 (first year of production). If it is pre-wired for LED headlights it doesn't mean you can swap them in...you will also need the correct Main Body ECU so you don't get error messages...like you're having now.
