If a light bulb in one of the headlights of your Honda Civic burns, you will have to replace it immediately for legal and safety reasons. If the box containing the headlights and other bulbs is cracked or broken, it is a good idea to replace it with a new unit. This idea is especially true with a tail light, where a broken housing must be fixed or covered with colored tape by law. Changing a bulb in a 2005 model is a simpler process than with some older models; However, replacing a housing unit will have some extra work.
Open the hood, once you have confirmed that both the headlamp and the ignition switch have turned off.
Disconnect the headlight electrical connector from the bulb socket.
Disconnect the bulb from the box by turning it 45 degrees to the left and then pulling it.
Remove the front bumper cover by removing all bolts, screws, and other fasteners at the bottom edges, the fender well, and the top edge.
Remove the four combined upper and lower mounting screws of the housing with a wrench, unplug the led bulb electrical connectors, the turn signal and parking lights and remove the housing.
Separate the small, black bumper corner beam from the housing by removing its bolt then install it in the replacement housing.
Install the replacement headlight housing on the car, connect the electrical connectors, and tighten the mounting bolts.
Reconnect the front bumper cover with all its fasteners.
Tips and Warnings
- You may need to increase the front of the vehicle and rest it on adjustable brackets to access lower bolts/screws on the bumper cover.
