Upgrade Your Audi A4 B9 / A4L / S4 / RS4 (2017–2019) with LED Headlights Featuring Start-Up Animation & Dynamic Turn Signals

Why Audi A4 B9 Owners Are Upgrading Their Headlights in 2026

If you own an Audi A4 B9, A4L, S4, or RS4 from the 2017–2019 model years, you already know the car is a masterpiece of German engineering. But factory headlights — even on a premium vehicle — can fall short of the visual impact and functionality that modern LED technology delivers.

More and more Audi enthusiasts are turning to aftermarket LED headlight assemblies to give their cars a refreshed, high-end look that rivals newer model years — without a full vehicle upgrade.

What Makes These LED Headlights Stand Out?

✦ Start-Up Animation

One of the most sought-after features in modern luxury vehicles is the welcome/start-up light animation. These headlights deliver a dynamic sequential light sequence every time you unlock or start your car — a signature detail that turns heads in any parking lot.

✦ Dynamic Front Turn Signals

Replace static amber blinkers with flowing sequential LED turn signals. The sweeping animation improves visibility for other drivers while giving your A4 a distinctly modern, RS-inspired aesthetic.

✦ Full LED DRL (Daytime Running Lights)

Crisp, bright LED DRLs improve daytime visibility and give your Audi a distinctive road presence — consistent with the look of newer Audi models.

✦ Plug & Play Installation

These headlights use the same connectors and wiring harness as your factory units. No cutting, no splicing — direct bolt-on fitment for 2017, 2018, and 2019 Audi A4 B9 / A4L / S4 / RS4. Professional installation is recommended for best results.

✦ Complete Assembly — Both Sides Included

The package includes a full pair (left + right) of LED headlight assemblies, so you get a perfectly matched set right out of the box.
