Headlights are mostly unglamorous parts of automobiles. We rarely give them a thought until they burn out while we're driving down a narrow, dark road at night or through the gloom of thick fog. You should check your vehicle's lights regularly and replace any burned-out bulbs immediately. Replacing the headlight bulb on the 1998 Nissan Sentra is a relatively uncomplicated task requiring no tools and just a small investment of your time.
Locate the headlight socket. This is at the very front of the vehicle and plugs into the lens assembly. It will have two wires leading into it.
Remove the headlight socket by turning it counterclockwise and pulling it straight out.
Remove the bulb from the socket by pressing the locking tab and pulling the bulb out of the socket with your hands.
Push the new bulb into the socket using your hands. Do not touch the glass part of the bulb assembly, as this can cause the bulb to blow out prematurely. Press on the plastic part of the bulb.
Push the socket back into the hole from which came and twist it clockwise to lock it into place.
