Headlight units.

[Ajcman]

This may be a stupid question but don't grill me to much

I've an A3 with the standard head light units, I would like to swap them out for the units that have the LED strips and xenons.

Will they just fit straight over or will there need to be some jiggery pokery?

Change them then code them and wiring needs changing.
Not hard but not plug and play.
Lots of people do retrofits on here NHN did mine.

Fit the unit, coding, level sensors
