Can You Put LED Bulbs in a 2004 Dodge Ram 4500?

Upgrading to LED is one of the most effective ways to modernize your Dodge's appearance and safety profile. Since your Ram 4500 uses a single 9007 LED bulb for both high and low beams, ensure your chosen LED kit is "dual-beam" compatible. This allows the LED circuitry to mimic the two-filament design of the original halogen bulb. 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 9006 LED fog lights; switching these to LED can dramatically improve your visibility in adverse weather.
