🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm you have the correct bulbs

• Use your flashlight to look behind each headlight for a removable round rear cover (the “dust cap,” which seals the housing).
• If you see a removable dust cap and a twist-lock bulb, you have serviceable halogen bulbs.
• If you do not see a removable bulb/socket and the back looks like a sealed LED unit, skip to Step 9.

Step 2: Create working room on the left headlight (driver side)

• Use a flat trim tool to gently unclip and move any nearby plastic ducting that blocks your hand access.
• If the washer fill neck is in the way, pull it upward to unclip it from its holder (it’s designed to move for service).
• Tip: Move parts gently; don’t force clips.

Step 3: Remove the left headlight dust cap

• Reach behind the left headlight and remove the dust cap by turning it counterclockwise by hand.
• Set the cap where it won’t get dirty (it needs to seal well).

Step 4: Remove the left headlight bulb

• Disconnect the bulb electrical connector by pressing the tab and pulling straight back.
• Twist the bulb counterclockwise (usually about a quarter-turn) and pull it out.
• Tip: Note the tab positions before removal.

Step 5: Install the new left bulb (no touching glass)

• Put on nitrile gloves before handling the new bulb.
• Optional: apply a tiny amount of dielectric grease to the connector seal (it helps prevent moisture and corrosion).
• Insert the new bulb in the same orientation, then twist clockwise until it locks.
• Reconnect the electrical connector until it clicks.

Step 6: Reinstall the left dust cap

• Install the dust cap and turn it clockwise until fully seated and sealed.

Step 7: Create working room on the right headlight (passenger side)

• If access is tight, use the 8mm socket, 1/4" ratchet, and 6" extension to loosen the intake hose clamp just enough to move the air intake duct a little.
• Move the ducting aside without kinking or cracking it.

Step 8: Replace the right bulb (same method as left)

• Remove the dust cap by hand (counterclockwise).
• Disconnect the connector, twist the bulb out, and remove it.
• Install the new bulb (gloves on), twist to lock, and reconnect the connector.
• Reinstall the dust cap fully seated.

Step 9: If your Renegade has LED headlights (bulb not serviceable)

• If there is no removable bulb/dust cap and the unit appears sealed, the “bulb” is part of the headlamp assembly/module.
• At that point, replacement typically involves replacing the headlamp assembly and may require aiming/calibration afterward.
• If you tell me whether your headlights are halogen or LED, I’ll give you the exact correct procedure path.

Step 10: Reconnect battery (if disconnected)

• Reinstall the negative battery terminal using a 10mm wrench.
• Torque to 5 Nm (44 in-lbs)

✅ After Repair

• Turn the headlights ON and confirm both sides light up on low beam and high beam (as equipped).
• Check that both dust caps are fully sealed (helps prevent condensation inside the lens).
• At night, verify the beam pattern looks even and not aimed too high.
