A4 / S4 / RS4 / B9

Audi A4, S4 and RS4 B9 ambient lighting pages connect model-code searches with R28 fitting and compatibility checks. The useful route is to choose the matching product page when available or request a quote with the vehicle year, trim and current factory lighting.

R28 Custom Garage focuses on supplied-and-fitted ambient lighting, starlight roof and interior lighting upgrades for UK customers. These model pages are kept indexable because they already show real search demand and have a commercial path to booking.
