BMW G30 LCI Headlight Retrofit
Wiring, Coding & Fitment Guide
Planning an LCI headlight upgrade for your BMW G30? Before ordering the lights, check the current setup, connectors, wiring, coding and market specification.
Start With The Right Setup
Changing the headlights on a BMW G30 is more than a visual upgrade. The selected LCI headlights need to suit the vehicle physically and electrically, and the car may need to be configured for the new equipment.
A pre-LCI G30 can be converted to LCI headlights, but the retrofit path depends on the original lighting system and the exact LCI headlights being installed.
If you are planning a complete exterior conversion, see our BMW G30 Facelift Conversion Guide.
If you are upgrading the rear lighting as well, see our BMW G30 LCI Tail Light Retrofit Guide.
For a wider list of components, see the BMW G30 LCI Retrofit Parts Guide.
What Determines G30 Headlight Compatibility?
The key factors are the original lighting system, the target LCI headlight version, connector and module compatibility, vehicle configuration and market specification.
For example, a pre-LCI G30 with Adaptive LED can have a different retrofit path from another lighting configuration. The LCI headlight version also makes a difference because different versions can use different functions and modules.
For more detail on coding, control modules and retrofit compatibility, see our BMW G30 LCI Retrofit Coding & Compatibility Guide.
G30 Headlight Retrofit Compatibility Guide
Use this table as a starting point. The final parts and wiring should always be confirmed against the individual vehicle and selected headlights.
| Current setup | Target | What to check |
|---|---|---|
| Pre-LCI G30 Adaptive LED | LCI Adaptive LED | Headlight version, connectors, wiring and coding |
| Pre-LCI G30 Adaptive LED | LCI higher-function lighting | Modules, wiring, vehicle configuration and available functions |
| Pre-LCI G30 other lighting setup | LCI headlights | Current equipment, connectors, adapters, wiring and coding |
| LCI Adaptive LED | Different LCI lighting version | Headlight modules, configuration and coding |
| US-spec vehicle | EU-spec lighting setup | Market-specific functions, configuration and local requirements |
The aim is to know what is needed before the installation starts. This is especially useful when the vehicle and the headlights come from different markets.
What Do You Need For A G30 LCI Headlight Retrofit?
The required components vary by starting configuration and target headlight version. The table below shows the main areas that should be considered.
| Part / Area | Typical situation | Why it matters |
|---|---|---|
| LCI Headlights | Main component | The selected lights need to match the vehicle and retrofit plan. |
| Wiring / Adapters | May be needed | Connector type and vehicle configuration determine how the lights are connected. |
| Headlight Modules | Setup dependent | The selected lighting version may require specific modules or configuration. |
| Coding / Configuration | May be required | The vehicle may need to be configured for the new lighting equipment. |
| Mounting / Related Parts | Conversion dependent | A complete facelift can involve additional front-end components. |
| Installation & Testing | Required | Fitment, functions, warnings, fault memory and headlight alignment should be checked. |
Our advice: define the complete retrofit combination before ordering individual components. This helps identify wiring, module and coding requirements in advance. For more information, see our BMW G30 LCI Retrofit Coding & Compatibility Guide.
Three Ways To Plan A G30 LCI Headlight Retrofit
The headlights can be treated as a standalone upgrade or as part of a larger facelift. Knowing the scope before ordering helps keep the parts and electrical work organised.
Headlights Only
The main goal is to replace the front headlights while keeping the rest of the exterior unchanged.
This can be a good option when the lighting upgrade is the main reason for the project.
Headlights + Related Parts
The headlights are planned together with the wiring, adapters, modules or other components needed for the selected setup.
This approach makes it easier to prepare the electrical side before installation.
Complete LCI Conversion
The headlights become part of a larger facelift project involving parts such as the front bumper, grilles, tail lights and other exterior components.
For the rear lighting upgrade, see our BMW G30 LCI Tail Light Retrofit Guide.
For the wider project, see our BMW G30 Facelift Conversion Guide.
Can A Pre-LCI G30 Use LCI Headlights?
Yes. A pre-LCI G30 can be converted to LCI headlights, but the retrofit path depends on the original lighting system and the selected LCI headlight version.
The exact retrofit path depends on the original lighting system and selected LCI headlight version. Depending on the combination, connector adaptation, wiring changes, module compatibility or coding may be required.
Will The Retrofit Need Wiring Or Coding?
The exact wiring requirements depend on the original lighting system and selected LCI headlights. Some combinations may require adapters or wiring changes.
For a deeper explanation of BMW G30 retrofit coding, module compatibility and configuration considerations, see our BMW G30 LCI Retrofit Coding & Compatibility Guide.
After installation, test the lighting functions, warning messages and fault memory. Headlight alignment should also be verified before normal road use.
Why The Vehicle Market Can Matter
The country or market for which the vehicle and headlights were supplied should be part of the compatibility check. This becomes particularly important when a vehicle is now being used in a different market.
European Specification
If the G30 was supplied for the European market, tell us where it was originally supplied and where it will be used.
US Specification
If the G30 was supplied for the US market, mention this even if the vehicle is now located in Europe.
Different-Market Headlights
If the vehicle and headlights come from different markets, provide the available part information and photos before ordering.
When vehicle and headlights originate from different markets, confirm the applicable lighting specification and configuration before installation.
What Should Be Checked After Installation?
Once the headlights are installed and the vehicle configuration has been completed, take the time to test the finished system properly.
Low Beam
Confirm that the main low-beam function operates correctly.
High Beam
Check the high-beam function and confirm that there are no related warnings.
Daytime Lighting
Check the relevant daytime lighting functions for the selected headlight configuration.
Turn Signals
Confirm that the applicable indicator functions operate correctly.
Additional Functions
Where applicable, test adaptive or other additional lighting functions supported by the selected setup.
Warnings & Fault Memory
Check the dashboard and vehicle fault memory rather than relying only on a visual inspection.
Headlight Alignment
Verify the final headlight aim after installation and adjustment.
Final Road Check
Make sure the system behaves as expected before returning the car to normal use.
Use Vehicle-Specific Technical Information
For installation work, use current vehicle-specific wiring diagrams, diagnostic procedures and programming information. Electrical and coding work should be carried out by someone familiar with BMW systems.
For official BMW technical information and service documentation, see BMW Technical Information.
