Modern automotive headlight bulbs last much longer than their predecessors, but eventually they will burn out and have to be replaced. If your 2006 Honda Accord has a burnt-out headlight, you need to repair it as soon as you can. Driving with only one headlight is both dangerous and illegal. The fine you could pay for this infraction is likely to be a lot more than the cost of a new bulb.
Open the bonnet to access the engine compartment. For passenger-side bulbs, you must first remove the air intake cover by unscrewing the two fasteners located at the top of the cover.
Depress the tab on the wiring connector and pull it down, off the bulb assembly.
Rotate the bulb one quarter-turn counterclockwise and remove it from the headlight housing. Insert the new bulb and lock it into place by rotating it one quarter-turn clockwise.
Reconnect the wiring to the bulb, ensuring that the tab snaps into place. If you were working on the passenger-side bulb, replace the air intake cover and connect the fasteners.
Start the car. If you are replacing a passenger-side bulb, turn the front wheels as far to the left as they will go. If you're working on the driver's side, turn the wheels to the right. Leave the wheels in that position and turn off the car.
Use a flat-tip screwdriver to pry out the centre portion of the two holding clips on the inner fender cover. Pull the cover back to access the headlight assembly.
Turn the bulb one quarter-turn counterclockwise and pull it from the assembly.
Depress the tab on the wiring connector and remove the bulb. Insert the new bulb into the connector.
Insert the bulb into the assembly and turn it one quarter-turn clockwise to lock it into place. Replace the inner fender cover and snap the holding clips back into place.
The high- and low-beam bulbs lie side by side, with the low beam towards the outside.
Do not touch the bulbs with bare hands. Doing so can leave behind oil that will shorten the bulb's life.
