Can You Put LED Bulbs in a 2020 Audi Q5 PHEV?

Upgrading to LED is one of the most effective ways to modernize your Audi's appearance and safety profile. We recommend starting your upgrade with the low beams, as they see the most use. Adding a matching H8 LED kit later will complete the look and ensure consistent lighting performance. Because Audi utilizes a CANbus system, standard LED bulbs may cause "bulb out" errors on your dashboard. Always opt for "Error-Free" or CANbus-ready kits which include the necessary resistors. Don't forget the 921 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
