The 2005 Honda Accord uses 9012 bulbs for its low-beam headlamps and 9011 bulbs for its high-beam headlamps. Each has a different installation process, but they are both fairly simple to perform. Be sure to replace your headlamps whenever they begin to malfunction as driving your Accord with bad headlights can be very dangerous and you could be involved in an accident. The replacement procedure requires the use of a flat-tip screwdriver and a cloth.
Turn the wheels as far inward as they can go. Remove the two holding clips from the inner fender with a flat-tip screwdriver.
Remove the inner fender cover away from the bumper and fender.
Pull the bulb out by rotating it counterclockwise. Remove the electrical harness from the bulb by pushing in on the lock tab. Attach the harness to the new bulb, making sure to use a clean cloth to install it.
Place the bulb back into the assembly and rotate it clockwise. Reattach the inner fender cover and the two accompanying clips.
Raise the bonnet. If replacing the passenger's side headlamp, be sure to remove the engine coolant reservoir by pulling it out of its slot.
Remove the electrical harness from the bulb by pushing in on the tab to unlock it and sliding the connector off of the bulb. Remove the bulb by rotating it counterclockwise.
Install the replacement bulb with a clean cloth and reattach the electrical harness.
Test the headlights to make sure they are functioning properly.
Replace the engine coolant reservoir if necessary and close the bonnet.
Always use a clean cloth to install the halogen bulbs. Failure to do so may result in a shortened performance life for the bulb.
