   • 2 Remove the cover from the high-mount brake light assembly, by hand. Pull the cover toward the front of the vehicle. Do not pull extremely hard, or you will break the clips that mount through the deck from the trunk.

The light will be fitted from inside the trunk. You might need to remove any trim or lining on the trunk lid. There will be 5 small nuts on the inside of the trunk lid. 2 each end and one centre. The light should drop out. It could be tight so GENTLY rock it up and down to free it.
** NOTE ** The light fitting is likely to be a sealed unit so you will have to replace the whole light as you cant get access to the bulbs.

Go to your local auto parts store.Ask at the counter,give them your make and model and year.

HMS Lamp will be mounted in roof or in rear parcel tray.

You have to locate the screws which will be closed/covered by a dummy cap. Remove the cap and unscrew the assembly, you will be able to replace the bulbs

1) You will need to open the rear swing door.

2) On the inside jam there are two torx headed screws (T-15's if I remember correctly).

3) Unscrew the two torx screws.

4) The light is now held by two mounting tabs (small spherical headed plastic sets that go through a rubber grommet).

5) You will need to pry the light casing off (easy pressure with a good size flat head screw driver will do the trick).

6) The light bulbs are twist mount settings inside the light casing.

7) Twist out the mount setting, change the bulbs, and reset the light mountings.

8) To put the light casing push the light casing back on and put in the screws. Everything else will work in reverse when it comes to assembling the whole unit.
