There's a new aftermarket headlight that has the LED strip stretch out more to the outside and does a more graceful curve up. On eBay, they've added the aftermarket HID kit to make it a total package. People though, rightfully, were concerned since nobody's ever seen one on a car.
You can see that it's not as deep as the S4 ecodes. It's about as deep as regular A4 xenon headlights. This can actually be a good thing for me. On my passenger side, the S4 ecode will push against my Neuspeed XTreme TIP. With the new headlight being shallow, the TIP shouldn't get bent which might make a tiny bit of improvement in airflow.
If you suspect that the positioning of your new headlight may have been disturbed while you changed it, have it checked before you drive at night. Otherwise, you are ready to go.
