Do these headlights plug directly into my existing wiring, or do I need an adapter harness?

Connector type and wiring compatibility are not specified in the product data. Before ordering, confirm your vehicle's current headlight connector matches these units, or source an appropriate adapter if needed.

Will these work with my factory light control module, or do I need a ballast or controller?

LED projector headlights often require specific wiring or control modules depending on OEM compatibility. Verify with your vehicle's electrical schematic or have a BMW-certified shop confirm before installation.

What's the return process if these don't fit or don't work once installed?

Contact ModSupply directly with photos and your order number. Most aftermarket headlights are returnable within 30 days if unopened and in resaleable condition — confirm the specific return window when you order.
