Buying Electrical Bulb & Socket Parts for a 2015 Audi R8

On this vehicle, the bulb and socket system covers every bulb and socket on the vehicle, from headlamps to instrument-cluster illumination.

  • Confirm you have the 4.2L V8 engine — every part on this page is matched to it.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace bulbs in pairs so both sides age together, and put a smear of dielectric grease on the new socket contacts.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

Our catalog currently lists 40 electrical bulb & socket parts for the 2015 Audi R8 across 10 subcategories and 5 brands, covering the 4.2L V8 engine. Each part is matched to the engine(s) it fits.

What are the signs of electrical bulb & socket problems on a 2015 Audi R8?

What should I replace at the same time?

Where labor overlaps, replace bulbs in pairs so both sides age together, and put a smear of dielectric grease on the new socket contacts.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 2015 Audi R8 was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 2015 Audi R8?
