LED Flicker Warning
This vehicle is known to use a CANbus system. Installing standard LEDs may cause flickering.
Can You Put LED Bulbs in a 2020 Volkswagen Jetta?
Upgrading to LED is one of the most effective ways to modernize your Volkswagen's appearance and safety profile. We recommend starting your upgrade with the low beams, as they see the most use. Adding a matching LED kit later will complete the look and ensure consistent lighting performance. Because Volkswagen 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 H11 fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
