Identify a replacement Mustang Mach-E LED module by checking the original component markings alongside the headlamp assembly reference and vehicle application. The model year, connector shape or appearance of the module alone does not confirm compatibility.
This guide explains which details to compare before ordering. If the faulty component has not yet been diagnosed, start with the Mustang Mach-E “Check Headlamp System See Manual” guide.
Identify the component before comparing numbers
Parts descriptions may use “headlight module,” “LED driver” and “headlamp control module” loosely. Establish which component the diagnosis concerns before searching for a replacement.
| Component | Identification detail |
| Complete headlamp assembly | Check the assembly reference on the lamp housing or identification label. |
| LED module | Check the markings on the module itself, including the complete part-number suffix. |
| Another lighting controller | Confirm its component name and reference through the applicable parts information. |
An assembly number and a module number identify different components. Do not use one as a direct substitute for the other.
Read the complete LED module label
Record the manufacturer name and every relevant identifier. Keep the final letters: a matching number prefix does not establish that two variants are interchangeable.
The FoMoCo LC5A-13B626-AG LED module has these identification references:
| Identifier | Part Numbers |
| FoMoCo module marking | LC5A-13B626-AG |
| Continental manufacturer number | A2C7636130500 |
| Listed Ford reference | LC5Z-13C788-E |
An engineering marking on the component and a service reference used for ordering can have different formats. Confirm their documented relationship rather than assuming that different-looking references identify different components—or that similar references identify the same one.
The identifiers above concern this LED module. They do not establish suitability for every Mach-E headlamp.
Match the module to the fitted headlamp
Compare the component markings with:
- The headlamp assembly reference.
- The vehicle’s VIN and model year.
- The fitted lighting specification.
- The vehicle’s market specification.
- The affected side, where relevant to fitment.
If the headlamp has previously been replaced, identify the assembly currently fitted. An assumed original trim specification may not describe the installed lamp.
Where a replacement has a different suffix or reference, confirm whether it is a suitable substitute for that application. Matching connectors or mounting points are insufficient.
What if the label cannot be read?
Use the headlamp assembly reference and vehicle details to obtain a parts lookup. Previous repair records may also identify the installed component.
If the label is inaccessible, consult the service information for the fitted assembly before removing parts. Access requirements should not be assumed from another Ford model or headlamp configuration.
Where the available details do not establish a match, resolve the identification before ordering from a general “Mach-E headlight module” description.
Check the replacement requirements
Once compatibility is established, check whether the replacement needs coding.
The LC5A-13B626-AG LED module specifications state that coding is required after replacement. See Mustang Mach-E headlight module programming after replacement for the information to confirm before installation.
Before ordering, establish the diagnosed component, its complete identifiers, the fitted headlamp application and the replacement requirements.
