The 2005 Honda Accord uses different light bulbs in each headlight assembly for the low beams and high beams. Changing a low beam bulb involves a different procedure than the high beam bulb. To ensure the correct bulb is being replaced, it's best to locate the faulty bulb before purchasing and replacing it in order to obtain the correct part. The bulbs look the same but are intended for different uses. The low beam bulbs are on the outer edge of the headlight assembly, and the high beam bulbs are on the inner edge.
Start the engine and turn the steering wheel in the opposite direction of the headlight being replaced. Turn it all the way to the right if replacing the driver's side low beam or all the way to the left if replacing the passenger's side low beam. Turn the engine off and ensure the headlight switch is in the "Off" position.
Remove the two retaining clips holding the inner fender splash cover with a flat head screwdriver. Pop the centre pin of the retaining clip upward then pull the clip assembly out of the fender splash cover.
Pull the fender splash cover away from the fender and bumper with one hand and reach in with the other hand to grasp the socket of the low beam headlight bulb.
Disconnect the wire harness plug from the headlight bulb by squeezing in on the sides to unlock it then pull it off the socket of the low beam headlight bulb.
Rotate the bulb socket a 1/4 turn counterclockwise to align its retaining tabs to the release grooves of the headlight assembly then remove the bulb.
Hold the replacement 9006 low beam headlight bulb by its socket to avoid touching the glass bulb. Oils and perspiration in skin will damage the bulb.
Align the retaining tabs of the bulb socket to the release grooves in the headlight assembly. Push slightly inward and rotate the socket a 1/4 turn clockwise to lock it in place. Reconnect the wire harness plug and test the headlight before replacing the retaining tabs of the fender splash cover.
Open the bonnet and remove the two retaining clips from the air intake cover on the passenger's side high beam with the screwdriver as noted in Step 3. For the driver's side high beam replacement, proceed to Step 2.
Detach the wire harness connection from the high beam bulb by squeezing the sides to unlock it then pulling it out of the bulb socket.
Rotate the socket of the headlight bulb a 1/4 turn counterclockwise to remove it from the headlight assembly.
Install the replacement 9006 headlight bulb (again, do not touch the glass bulb section) by reversing the removal procedure.
Reconnect the wire harness plug to the headlight bulb socket and test the headlight before replacing the air intake cover and retaining clips for the passenger's side.
