Headlight Bulbs - Pair

Replace both headlight bulbs on a 2014 Ram 2500 with 6.7L Cummins diesel engine, requiring partial headlight assembly access.

Warnings

Tools required

Parts

• H11 Halogen Headlight Bulb (Low Beam) × 2 — Use OEM specification or equivalent H11
• 9005 Halogen Headlight Bulb (High Beam) × 2 — Use OEM specification or equivalent 9005

Preparation

1. Park vehicle on level surface and turn off ignition
2. Allow headlight bulbs to cool completely if recently operated
3. Open hood and secure with prop rod
4. Identify which bulbs need replacement (low beam uses H11, high beam uses 9005)

Procedure

1. 1

   Access driver side headlight assembly
   Locate the headlight assembly from behind in the engine bay. On the driver side, you may need to move the air filter housing or coolant reservoir slightly for better access. The bulb sockets are accessible from the rear of the headlight housing.
2. 2

   Remove low beam bulb socket (if replacing low beam)
   Locate the low beam bulb socket on the inner portion of the headlight assembly. Rotate the bulb socket counterclockwise approximately 1/4 turn and pull straight back to remove from the housing. The electrical connector remains attached to the socket.
3. 3

   Disconnect low beam electrical connector
   Press the release tab on the electrical connector and pull away from the bulb socket. Remove the old H11 bulb by pulling straight out of the socket. Inspect socket for corrosion or damage.
4. 4

   Install new low beam bulb
   Using clean gloves or holding the bulb base only, insert the new H11 bulb into the socket. The bulb has alignment tabs that only allow correct orientation. Push firmly until fully seated. Reconnect the electrical connector until it clicks.
5. 5

   Reinstall low beam socket
   Align the socket tabs with the headlight housing slots and insert straight in. Rotate clockwise 1/4 turn until it locks into place. Verify the socket is secure and cannot be pulled out.
6. 6

   Remove high beam bulb socket (if replacing high beam)
   Locate the high beam bulb socket on the outer portion of the headlight assembly. Rotate the bulb socket counterclockwise approximately 1/4 turn and pull straight back to remove from the housing.
7. 7

   Replace high beam bulb
   Disconnect the electrical connector from the high beam socket by pressing the release tab. Remove the old 9005 bulb by pulling straight out. Using clean gloves, install the new 9005 bulb into the socket, ensuring proper alignment with the tabs. Reconnect the electrical connector until it clicks.
8. 8

   Reinstall high beam socket
   Insert the high beam socket straight into the headlight housing, aligning the tabs. Rotate clockwise 1/4 turn until locked in place. Verify secure installation.
9. 9

   Access passenger side headlight assembly
   Move to the passenger side of the engine bay. Access is typically easier on this side. Locate the bulb sockets on the rear of the passenger headlight assembly.
10. 10

    Replace passenger side bulbs
    Repeat steps 2-8 for the passenger side headlight assembly. Follow the same procedure for removing sockets, disconnecting electrical connectors, replacing bulbs with clean gloves, and reinstalling sockets with proper rotation and locking.

Reassembly

1. Ensure all bulb sockets are rotated and locked into place on both headlight assemblies
2. Verify all electrical connectors are fully seated and clicked into place
3. Return any moved components (air filter housing, coolant reservoir) to original position
4. Close hood securely

Verification

• Turn ignition to ON position without starting engine
• Activate headlights and verify both low beams illuminate properly
• Switch to high beams and verify both high beams illuminate properly
• Check for proper beam pattern alignment - bulbs should be seated correctly if pattern is normal
• Turn off all lights and remove key from ignition
• Visually inspect from front of vehicle that both headlights are functioning with no dark spots or abnormal lighting
