AI-READY FITMENT SUMMARY
Quick Answer
Question: Can Porsche 911 991 Headlight Upgrade be used on my vehicle?
Answer: Potentially, yes. This upgrade can be used when the vehicle, original equipment and replacement-part configuration match. Final compatibility must be confirmed before purchase or installation.
Compatibility depends on:
- VIN, model year and production date
- Original connector, OEM reference and installed hardware
- Factory options such as adaptive lighting, sensors, cameras or heating
- Coding, calibration and workshop capability
- Destination-market regulations and road-use requirements
Evidence to provide: VIN, clear photos of the original part and connector, OEM label or part number, dashboard option screens, and any diagnostic scan relevant to the upgrade.
Quick answer: Porsche 911 991 headlights must be verified by 991.1 or 991.2 generation, original xenon, PDLS or LED equipment, module family and market beam pattern. Styling similarity is not proof of electronic compatibility.
Fitment Table
| Check | Why it matters |
|---|---|
| 991.1 / 991.2 | Housing shape, bumper interfaces and electronics can differ. |
| Bi-xenon / PDLS / LED | Determines drivers, leveling and adaptive functions. |
| LHD / RHD | Controls the legal beam cutoff. |
| US / EU market | Marker and approval requirements differ. |
Pre-Order Evidence
Provide VIN, production month, lamp labels, rear-housing photos, connector views and a diagnostic scan. Confirm whether control modules are included or transferred and whether the vehicle currently has lighting faults or water damage.
Modules and PDLS Functions
Ask whether startup leveling, cornering behavior, high-beam assist and dashboard diagnostics remain supported. Reused modules must match the housing family and pass testing. Software coding cannot create missing optical or mechanical hardware.
Installation Notes
Protect painted edges, compare all mounting points, transfer only verified modules and bench-test functions before final assembly. Complete coding, calibration and professional beam aiming.
Compatibility Warning
Do not mix LHD and RHD optics or assume a US lamp is identical to an EU version. An incompatible beam pattern can create glare and fail inspection even when no warning appears.
Workshop Tips
- Inspect vents and rear caps.
- Use clean gloves on optical components.
- Keep moisture-damaged electronics out of the new housing.
- Save the original coding report.
- Retest after a warm operating cycle.
FAQ
Can 991.2-style lights fit a 991.1?
Only with a documented conversion system and any required surrounding parts.
Can PDLS be retained?
Yes only when the replacement supports the original modules, sensors and functions.
Is beam aiming required?
Yes. Physical installation alone does not establish safe aim.

Compatible Product
This guide relates to Porsche 911 991 PDLS smoked LED headlights with AFS module and wiring harness.
Fitment can vary by model year, trim, factory options and market. Please verify your VIN and current configuration before ordering.
Product Association
This guide is linked to the Porsche product collection and the lighting products. A related listing is not automatic proof of fitment. Match the chassis, production date, original equipment, connectors, modules and included accessories before ordering.
OEM Reference
| Reference item | Required evidence |
|---|---|
| Original part number | Clear photo of the complete OEM label, including left/right suffix and revision. |
| Module or controller | Module label, software/hardware index and connector photo where applicable. |
| Vehicle production split | VIN or production month, market version and original option level. |
Status: OEM numbers are verification inputs, not universal interchange promises. Do not order from a partial number or model name alone.
Installation Evidence
- Before: photograph the vehicle, original part, labels, connectors, mounting points and dashboard warnings.
- During: record dry-fit alignment, harness routing, adapter/module placement and any coding or calibration step.
- After: provide installed photos plus a function video covering lighting, sensors, cameras, controls and warning messages.
- Stop and re-check if a connector, bracket, gap, function or included accessory differs from the approved evidence.
