H7 HID Adapters: BMW E39

The BMW E39 HID Bulb Adapter Rings are designed to simplify the installation of aftermarket HID conversion bulbs in select BMW E39 headlight housings. Because the factory H7 halogen bulb mounting system uses a unique retaining and connector extension design, standard HID bulbs cannot be installed correctly without the proper adapter.

These precision-molded adapter rings provide a secure OEM-style fit, allowing your HID bulbs to lock firmly into the factory housing while maintaining proper bulb alignment for optimal beam pattern and lighting performance.
