Use a CANbus decoder.

Can You Put LED Bulbs in a 1991 Dodge Dakota?

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 H4666 LED low beams, as they see the most use. Adding a matching 161 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 H3 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
