How to Choose the Right Version?

Please select the correct regional standard (SAE vs ECE) to pass your local vehicle inspections.

Two uninstalled Model Y Juniper headlight assemblies with clear upper strips displayed above a white vehicle.

The Rule: Check Your Country's Standard

Headlight regulations vary by region. The main physical difference is that North American (SAE) headlights feature an amber side marker/reflector, while International (ECE) headlights usually do not.

Choosing the correct version ensures your beam pattern complies with local laws and prevents issues during MOT, TÜV, or state inspections.

Need help selecting?

If you are unsure which standard applies to your country, please contact our support team before placing your order.

Frequently Asked Questions

Find answers to the most common questions about replacing your Juniper headlights.

Q1: Is this headlight compatible with the 2025-2026 Model Y Juniper (Refresh)?
Yes. This headlight is specifically designed for the Model Y Juniper (2025+) split-headlight system. It is a direct replacement for the Lower Main Beam Unit.

LH OEM Part Number: 1918347-00-D / 1918347-00-E
RH OEM Part Number: 1918348-00-D / 1918348-00-E

Note: This unit is separate from the upper center light bar (2038294-00-C). If you also need to replace the center bar, see our Front Center LED Light Bar (PN 2038294).
Q2: Does this aftermarket headlight support Matrix LED & Adaptive High Beam functions?
Absolutely. Our advanced aftermarket units are engineered to be fully compatible with Tesla's Matrix LED protocol. When enabled in your vehicle settings, it supports pixel-level dimming and adaptive high beam patterns to avoid blinding oncoming traffic, just like the original factory unit.
Q3: Will I get error codes after installation or OTA software updates?
No. We have integrated a high-spec driver module that communicates seamlessly with the Tesla vehicle gateway. It has been tested on Firmware 2026.x to ensure no "Headlight Fault" or "AFS Error" codes appear after installation or future Over-the-Air (OTA) updates.
Q4: Do I need to perform a "Software Reinstall" after replacing the headlight?
Yes. For the vehicle to recognize the new hardware ID and calibrate the beam level, we strongly recommend entering Service Mode on your touchscreen and initiating a "Software Reinstall". This is a standard Tesla procedure for both OEM and aftermarket headlight replacements.
Q5: What is the difference between the ECE and SAE versions?
  • SAE Version: Designed for the North American market (USA/Canada), featuring the required side reflectors.
  • ECE Version: Designed for Europe, Asia, and other regions, following international beam pattern standards.
Please ensure you select the correct region version to pass local vehicle inspections (e.g., MOT or TÜV).
Q6: Does it include the internal LED driver module?
Yes, our Juniper headlight comes as a complete assembly with the integrated LED driver module. It is a 100% "Plug-and-Play" solution, so you don't need to swap modules from your old, damaged headlight.
