Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old H4666 LED bulb counter-clockwise to remove it, then insert the new bulb and reassemble. Note: Dodge vehicles use a CANbus system, so LED replacements may need an anti-flicker decoder. The whole process typically takes 10 to 30 minutes per side depending on accessibility.

LED bulbs used off-road or in auxiliary lights are legal everywhere. For on-road headlight use, legality varies by state.

LED Flicker Warning

This vehicle is known to use a CANbus system. Installing standard LEDs may cause flickering.

Use a CANbus decoder.

Can You Put LED Bulbs in a 1990 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.
