Turn off the vehicle and open the hood. Locate the headlight assembly from behind, remove the dust cover or retaining clip, disconnect the wiring harness, twist the old HID-D3S 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.

Are LED headlights legal for a 2018 Dodge Challenger?

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

What is the difference between halogen and LED for a 2018 Dodge Challenger?

Halogen bulbs produce a warm yellow light (around 3200K), last 500 to 1000 hours, and draw more power. LED bulbs emit a brighter white light (5000-6000K), last 25,000+ hours, and use less energy. LED upgrades for the HID-D3S LED position are available as direct plug-and-play replacements. Since the Dodge uses CANbus monitoring, choose a CANbus-compatible LED kit to avoid dashboard errors.
