Can You Put LED Bulbs in a 2009 Mercedes-Benz G55 AMG?

Upgrading to LED is one of the most effective ways to modernize your Mercedes-Benz's appearance and safety profile. We recommend starting your upgrade with the H4 low beams, as they see the most use. Adding a matching LED kit later will complete the look and ensure consistent lighting performance. Because Mercedes-Benz 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.
