Can You Put LED Bulbs in a 1990 Dodge Dynasty?

Upgrading to LED is one of the most effective ways to modernize your Dodge's appearance and safety profile. We recommend starting your upgrade with the 9004 LED low beams, as they see the most use. Adding a matching 194 LED kit later will complete the look and ensure consistent lighting performance. Because Dodge 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 LED Fog Light fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
