This downgrade wiring loom is designed for vehicles that were originally fitted with Xenon headlights and are now being converted to Halogen headlights. It allows the halogen lamps to be fitted correctly using the original vehicle wiring without the need for custom splicing or permanent modification.
Designed specifically for converting from Xenon to Halogen headlamps using a proper adapter loom.
Key Information
- ✅ Specific adapter for downgrading from Xenon to Halogen headlights
- ✅ Plug & Play – no cutting or splicing required
- ✅ Only one loom required for both headlights
- ✅ Uses OEM-style connectors for reliable fitment
- ✅ High-quality wiring and connectors
This loom is designed to be plug & play for standard Xenon-to-Halogen conversions.
If your vehicle was originally equipped with adaptive Xenon / AFS headlights, the AFS function will need to be disabled and the AFS module disconnected as part of the conversion.
Coding requirements depend on vehicle configuration and are not supplied with this loom.
Vehicle Compatibility
- Audi A4 B7 (2004–2008)
This product provides the hardware solution for the downgrade. Any required coding is the software side of the retrofit and should be carried out by a qualified technician if needed.

Optional Fitting Service
