The 2014 Audi S5 uses a mix of LED lighting and replaceable bulbs depending on the location. That means some lights are listed by bulb type while others are integrated LED units, so checking each position carefully is the best way to avoid ordering the wrong replacement.
Fitment can vary by trim, lighting package, market, and body style, so always compare the bulb position on your car with the chart before purchasing.
