If you’re behind the wheel of a B9 Audi S5, you already know the vibe. It’s a fast, sharp, and clean-looking machine—basically a sleeper sports car in a tux. But even the sharpest cars need a little love over time, and one of the most underrated upgrades you can make is swapping out your headlights. Whether you’re fixing damage, upgrading for better night vision, or just want to stand out a bit more, finding the best headlight replacement for Audi S5 B9 can totally transform your ride.
This blog is going deep. We’ll cover everything—from OEM vs aftermarket comparisons, to best picks from Amazon and AliExpress, installation steps, common issues, and even some mod ideas while your bumper’s off. Let’s get into it.
Why Upgrade Your S5 B9 Headlights?
Let’s break it down—Audi already gave the B9 some slick full LED headlights stock. So why even bother?
- Style Upgrades: Even stock LEDs can look outdated next to modern matrix or animated setups.
- Cracked or Foggy Housings: Rock chips and UV wear add up.
- Better Visibility: Some aftermarket LEDs offer sharper beams with higher lumen counts.
- Customization: Want startup animations, smoked housings, or RS-style DRLs? OEM won’t get you there.
- Cheaper Than Dealer Fixes: OEM replacements can be over $1,500 PER headlight. Aftermarket is often better and cheaper.
I’ve helped a few friends mod their B9 S5s, and it’s crazy what a difference fresh headlights make. It’s like giving your car a face-lift.
Quick Specs – Audi S5 B9 Headlights

OEM vs Aftermarket: What’s the Move?
🛠️ OEM Pros:
- 100% guaranteed fitment
- Zero coding or errors
- Perfect if you’re restoring the car
❌ OEM Cons:
- Ridiculously expensive ($3,000+ for both sides)
- You get the same look—not much visual impact
⚡ Aftermarket Pros:
- Better value
- You can change the vibe of your front end completely
- Smoked housings, sequential DRLs, startup animations
⚠️ Aftermarket Cons:
- You may need OBDeleven or VCDS to code features properly
- Fitment varies (ALWAYS check reviews)
If you’re going for function + style + not going broke, aftermarket wins 90% of the time.
What to Look for in the Best Headlight Replacement for Audi S5 B9
Here’s a simple checklist:
- Fitment for 2018–2023 B9 chassis
- LED or laser projector (brighter than halogen or HID)
- Sequential turn signals (clean and modern)
- Start-up animation (some lights have a full “sweep” effect)
- Smoked/black housing for a stealthier look
- DOT/SAE compliance if you’re in the US
Don’t just go for looks—make sure the light output and beam pattern are solid. Cheap lights may look cool but perform terribly at night.
🔥 Top Pick on Amazon: Morimoto XB LED Headlights
- Designed for Audi S5 B9

- Black OEM+ housing
Why it’s great:

- Incredible visibility at night
Downside? They’re pricey. But you get what you pay for.
🔥 Top Pick on AliExpress: VLAND RS-Style LED Projector Headlights
- Full LED projection

Installation Walkthrough (DIY Guide)
What You’ll Need:
- Torx bits (T25/T30)
- 10mm socket
- Trim removal tools
- OBDeleven (optional for coding)
- Patience (bumper removal isn’t hard, just tedious)
Step-by-Step:
- Pop the hood and disconnect the battery
- Remove screws along the top of the bumper and under the fenders
- Pull off the bumper carefully
- Remove 3–4 bolts per headlight
- Unclip wiring harnesses
- Install new headlights, secure with bolts
- Plug in wiring and test all functions
- Use OBDeleven to disable bulb errors or tweak DRL behavior
- Reattach bumper, align panels, and you’re done
Install takes 2–3 hours. If you’ve never done it, look up a quick YouTube guide for visuals.
Common Problems and How to Avoid Them
- Buying A5 headlights: They’re similar but might not fit perfectly on the S5 due to grille shape.
- Skipping coding: DRLs or blinkers might flicker or not work
- Ignoring condensation: Make sure your new lights have a good seal
- Forgetting about leveling: Some kits need to be manually adjusted to aim properly
Mods to Add While You’re There
Once your bumper is off, knock out a couple other mods at the same time:
- RS5-style honeycomb grille
- LED fog light upgrade
- Carbon fiber front splitter
- Black Audi rings or badges
- Front camera or radar upgrade
Bundle your upgrades and save yourself the trouble of pulling the bumper again later.
