If the headlights in your 2005 Honda Civic are dim or one has stopped working, you can purchase replacement bulbs at most auto parts stores. Accessing the headlight bulb from the engine compartment side of the headlight assembly will allow you to remove the bulb without having to remove the entire assembly. It is important to change the headlights in pairs for the best possible results. If you want more visibility from your headlights, consider upgrading to a brighter light when replacing the bulbs.
Locate and remove the power steering reservoir from behind the driver's side headlight assembly. Pull straight upward, sliding it off its mount and set aside for access to the headlight bulb. Make sure you keep it upright so it does not spill.
Locate and remove the electrical connector from the back of the bulb. Depress the locking tab to release it and pull the connector down, removing it from the bulb.
Turn the bulb counterclockwise ¼-turn then pull the bulb straight out of the headlight assembly. Insert a new bulb into the headlight assembly and turn it ¼-turn clockwise to lock it in place.
Install the electrical connector by plugging it into the bottom of the bulb. Push the connector in until the locking tab engages the bulb, securing it to the bulb.
Slide the power steering pump reservoir onto its mount. Move the passenger's side of the car to replace the second bulb.
Loosen the battery hold down with a socket and ratchet. Slide the battery toward the windshield of the car to allow access to the passenger's side headlight.
Remove the electrical connector from the headlight bulb after releasing the locking tab. Turn the bulb ¼-turn counterclockwise and remove the bulb from the headlight assembly.
Insert a new bulb, turn it clockwise to lock the bulb into the assembly and connect the electrical connector to the bulb. Make sure the connector locks onto the bulb.
Slide the battery back into position and tighten the mounting bolt on the battery hold down with a socket and ratchet. Test the headlights by turning on the switch. Try them in both high beam and low beam to verify they are working correctly.
