How to Fix the Tail Light on a Ford Focus?

The lens needs to be removed. Look behind the trunk liner/carpet covering the access to the retainers holding the lens in place. Remove the retainers ( could be plastic wing nuts or actual nuts screwed to the tail light studs. ) There may be 3-5 holding the lens in place. Once retainers are removed the lens will pull away from the vehicle and the light socket can be twisted and removed from the lens assembly exposing the bulb

Hello,
In order to replace the light bulbs you will have to remove the entire rear light housing unit. In order to do this you must do the following:

1.Open the trunk.

2.Loosen the trunk lining in order to reach the 4 nuts that are located on the right or left side and hold the light housing in place.


3.You loosen the trunk lining fabric by removing two small, black plastic fasteners that anchor the trunk lining fabric. These either screw loose or you will need to pop off using a blunt- nosed pliers ( a flat head screwdriver works in a pinch) by first pulling the square bit out (towards the direction of the back seat,) followed by the circular components.


4.Pull the fabric loose on either the left or right side to expose the 4 nuts holding the light assembly in place.


5.Now, look for the four gold colored washer and nut assemblies surrounding the tail-light assembly. Find yourself a 7/16 socket and remove those washers and nuts. The tail-light itself should be able to pop- out, otherwise you've missed a washer- nut.


6.Ease the tail- light assembly off of it's perch on the car and hold it red- side down. This will expose the wiring and "turn- locks" for the blinker and tail- light.


7.Remove the bulbs from the assembly by turning the turn- locks in the direction (counter- clockwise) indicated by the plastic molding, and pulling upwards, off of the tail- light assembly.


8.Pull the bulb from the turn- lock with a moderate tug of the hand.


Problem solved.

Thank you for using fixya..

You go through the trunk and on either side is the light housing unit that you remove 4 nuts from, pull out and there will be the individual bulbs to be replaced.

open trunk lid inside there will be 5 or 6 large plastic thumb screws remove them and either 1/2 or the whole assy will come out,you'll have to remove wires on assy to replace lamps

From Inside The Trunk Or Hatch Whichever You Prefer. Locate The Panel Or Carpeting. It Will Be Directly Behind Where The Light Is Located Only On The Inside. Remove That Panel And Or Carpet And Youll Find Three Bolts Holding The Unit In Place.
