How to Replace Both Headlight Bulbs on a 2018 Dodge Charger (Low & High Beam)
Step-by-step wheel-well access instructions, required tools/parts, HID vs halogen notes, and safety tips
đź”§ Charger - Headlight Bulb Replacement (Both Sides)
On your Charger, the headlight bulbs are accessed from behind the headlamp through the front wheel-well liner (inner fender). You’ll replace the bulb(s) on the left and right sides the same way, then verify aim and operation.
Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours
⚠️ Safety & Precautions
- ⚠️ If equipped with HID bulbs, they run high voltage—turn lights off, remove key, and disconnect the battery before unplugging anything.
- ⚠️ Support the car with jack stands before working near/behind a wheel.
- ⚠️ Do not touch the glass on halogen/HID bulbs; skin oil can shorten bulb life.
- ⚠️ Let the headlamp area cool if lights were recently on.
đź”§ Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)

đź“‹ Before You Begin
- Park on level ground, set the parking brake, and chock the rear wheels.
- Turn the steering wheel toward the side you’re working on (gives more room in the wheel well).
- If your Charger has HID headlights, disconnect the battery negative cable before starting.
- Tip: Replace bulbs in pairs for matching color.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Identify which bulb type you have
- Open the hood and look at the back of the headlamp area.
- If you see a large igniter/ballast-style connector and “HID” labeling, follow the HID path below. Otherwise, follow the Halogen path.
- Tip: Match the bulb you remove to the new one.
Step 2: Raise the front corner (recommended for space)
- Place wheel chocks behind the rear tires.
- Use a floor jack (rated 3-ton minimum) to lift one front corner.
- Set the car onto jack stands (rated 3-ton minimum) before reaching into the wheel well.
Step 3: Remove enough of the inner fender liner to access the headlamp
- Use an 8mm socket with a 3/8" drive ratchet and 6" socket extension to remove the small bolts along the front section of the liner.
- Use a trim clip removal tool to pop out any plastic push-clips. (A trim clip tool is a small forked tool that lifts plastic clips without breaking them.)
- Pull the liner back just enough to reach the rear of the headlamp.
- Tip: A flashlight makes this much easier.
Step 4 (Halogen path): Remove the bulb
- Put on nitrile gloves.
- Reach to the back of the headlamp and locate the bulb socket/connector.
- Twist the bulb counterclockwise to unlock it, then pull it straight out.
- Disconnect the electrical connector from the bulb (press the tab and pull).
Step 5 (Halogen path): Install the new bulb
- Connect the wiring connector to the new bulb until it clicks.
- Insert the bulb into the headlamp and twist clockwise to lock it.
- Make sure the bulb sits fully flush; a crooked bulb will aim poorly.
Step 6 (HID path): Power down and remove the HID bulb
- Disconnect the battery negative terminal using an 8mm socket.
- At the rear of the headlamp, carefully disconnect the HID electrical connector.
- Twist the HID bulb/retainer counterclockwise to unlock, then pull the bulb straight out.
- Tip: Do not force the connector—recheck the lock tab.
Step 7 (HID path): Install the new HID bulb
- With nitrile gloves on, insert the new HID bulb without touching the glass.
- Twist clockwise to lock the bulb in place.
- Reconnect the HID connector securely.
- Reconnect the battery negative terminal using an 8mm socket.
Step 8: Reinstall the inner fender liner
- Reposition the liner.
- Reinstall bolts using an 8mm socket and clips using a trim clip removal tool (press clips back in by hand after aligning).
Step 9: Repeat on the other side
- Turn the steering wheel the opposite direction and repeat Steps 2–8 for the other headlight.
Step 10: If you removed a wheel (optional method), torque lug nuts
- Install the wheel and hand-start lug nuts.
- Lower the car and torque lug nuts using a torque wrench (10-150 ft-lbs): Torque to 176 Nm (130 ft-lbs).
âś… After Repair
- Turn headlights on and verify low beam and high beam work on both sides.
- Check that the bulb is not flickering and that the connector is fully seated.
- At night, confirm both beams aim evenly; mis-aim usually means the bulb isn’t fully seated/locked.
- Tip: Keep old working bulb as an emergency spare.
