Tesla Headlights Ultimate FAQ Guide
Part 1: Purchasing and Installation
Q1: How do I choose the correct replacement headlights for my Tesla?
To ensure a perfect fit, you should use the part number of your existing headlight or your vehicle's VIN (Vehicle Identification Number) to find the correct replacement part. This guarantees the new headlight will match the original factory-installed one.
Q2: Should I buy Full LED Headlights or Matrix Headlights?
We provide original replacement parts. Please identify your current headlight type using its part number or by comparing it to images. You should purchase the corresponding part to ensure full compatibility and functionality.
Q3: Can I upgrade my standard headlights to Matrix headlights with a simple part replacement?
No, upgrading from non-matrix to matrix headlights is not supported through simple part replacement, as it requires system-level compatibility and matching.
Q4: Are your headlights new or used? Does the headlight's appearance match the original part?
We sell brand-new Tesla parts. Each headlight undergoes strict quality checks before it's shipped, so you can order with confidence. The headlight's appearance is an exact match for the original part. Our products are designed as direct replacements, ensuring that they fit perfectly and have the same look as the original factory-installed headlights.
Q5: Is the Replacement Headlight for Tesla new or used, and is it a full assembly?
It is new and full headlight assembly (includes ballast and related hardware).
Q6: Do your headlights fit both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) vehicles?
Our headlights are designed to be suitable for both LHD and RHD vehicles. The difference in the beam pattern is visually imperceptible and does not affect driving safety.
Q7: I installed your Model 3/Y headlight part, but the lights are displaying abnormally or showing a fault. What should I do?
This issue can occur if the new part needs to be paired with your car's control system. Please follow these troubleshooting steps in order:
- Perform a Software Re-Pair: Enter Service Mode on your Tesla, click on "Software Upgrade," and run the process. Check if the lights return to normal function afterward.
- Advanced Troubleshooting: If the first step does not work, continue by swapping the connectors to the other side to see if the lights turn on. You can also interchange the left and right modules to diagnose the issue.
Part 2: Technology and Features
Q8: What technology do Tesla headlights primarily use?
Tesla headlights mainly use LED technology, and some higher-end models may feature Matrix headlights for precise beam control or Adaptive Turning Headlights that swivel to illuminate curves.
Q9: What smart features do Tesla headlights have?
Tesla headlights come with "Auto Headlights" that turn on/off based on ambient light and "Auto High Beams" that seamlessly switch between high and low beams. They also include Daytime Running Lights (DRLs) and "Follow Me Home" / "Welcome Home" lighting.
Q10: What is the typical lifespan of a Tesla LED headlight?
LED headlights are known for their exceptional longevity. A Tesla's LED headlights are designed to last for the entire lifespan of the vehicle, typically tens of thousands of hours, so a full replacement due to a burnt-out bulb is highly unlikely.
Q11: What's the difference between Matrix headlights and regular LED headlights?
While both are based on LED technology, Matrix headlights feature a grid of individually controlled LEDs. This allows the car to dynamically adjust the beam pattern, selectively dimming or shutting off specific LEDs to avoid dazzling oncoming drivers while maintaining high-beam illumination elsewhere on the road. Standard LEDs have a more uniform beam pattern.
Q12: Can I change the color or brightness of my Tesla headlights?
While aftermarket modifications are available, changing the color or brightness of your headlights is not recommended and may be illegal depending on local regulations. Most jurisdictions require headlights to emit white light within a specific brightness range for safety. Any significant alteration could compromise your visibility and violate traffic laws.
Q13: Do Tesla's adaptive headlights receive software updates?
Yes. Tesla's adaptive headlights can receive over-the-air software updates, which can introduce new features, improve their performance, and adjust their light patterns to comply with local regulations. This allows the headlights to evolve without the need for new hardware.
Part 3: Maintenance and Care
Q14: There is condensation or fog inside my Tesla headlight. Is this normal?
Minor fogging is a normal phenomenon caused by temperature differences and usually disappears on its own. However, persistent fogging or water droplets may indicate a compromised seal, and we recommend having it checked at a service center.
Q15: How can I maintain my Tesla headlights to extend their lifespan?
Regularly clean the headlights with a soft cloth and water, avoid using abrasive materials, and park your car in the shade to prevent lens degradation from sun exposure.
Q16: Can I replace just the headlight lens if it's broken?
No, the Tesla headlight is typically an integrated assembly. If the lens is broken, you need to replace the entire headlight assembly.
Q17: Why do Tesla headlights seem so bright, and is there a way to protect them?
Tesla headlights are designed to be very bright to maximize visibility and safety. The high-intensity LEDs are powerful, but this is a standard and intentional feature. To protect the headlight lenses from damage, a Paint Protection Film (PPF) is an excellent solution. This transparent film shields the lens from scratches, rock chips, and UV damage.
