Driving with a broken or burnt-out tail light is illegal and dangerous. You run the risk of getting a traffic ticket or worse, causing a serious accident. If the bulb is no longer working, replace it immediately. Honda has made it simple for do-it-yourselfers to replace tail light bulbs. Available as a coupe or sedan, the Honda Civic was introduced in 1973 and as of 2010 was in its eighth generation. Check with your specific year owner's manual for helpful diagrams.
Open the boot of your Honda Civic.
Remove the Phillips screw from the plastic fastener with a Phillips screwdriver. The screw is located at the top of the trunk lining in front of the tail-light assembly.
Remove the plastic fastener and pull back the trunk lining.
Turn the tail light bulb socket counterclockwise and pull it out of the tail light assembly.
Remove the old bulb. It pulls straight out of the socket.
Push the new bulb into the socket.
Reinstall the socket. Turn it clockwise to secure it in place.
Reverse steps 2 and 3 to finish.
Do not touch the glass part of the bulb. Oils from your hands can cause the bulb to shatter when it is turned on.
