Features and Construction

The plug is defined by its specific BMW part specification and the configuration options provided. Its design is focused on delivering a compatible electrical connection for the vehicle's headlight circuit.
Material and Build
The connector is constructed from materials typical for automotive electrical components, including a plastic housing for insulation and metal terminals for conductivity. The black colour classification is standard for such components, aiding in identification and matching the vehicle's existing wiring loom aesthetics. The build is centred on providing a secure electrical connection that meets the demands of the vehicle's lighting system.
Size and Practical Fit
The product’s key sizing specification is its part number: DJ7121W-1.5 2.8-21. This alphanumeric code denotes its precise electrical and physical compatibility with the BMW models listed. The option to choose a version 'with wire' or 'without wire' addresses different repair scenarios—one may be replacing just the connector body, while another might need a short section of wire attached. This choice adds practical flexibility to the purchase.
Uses and Placement

This component has a clearly defined application within the vehicle's electrical architecture, specifically for headlight connections.
Event or Professional Use
For professional mechanics, auto electricians, or experienced DIY enthusiasts, this plug serves as a exact-match replacement part.
