How do you gain access to rear light bulb on Toyota MR2 mk2?

Open your boot up and you'll notice that there is one screw at the top of the light cluster you want to access. Remove this.

Then go to the side. The little sideways V indicator lens at the front of the light assembly is separate from the rest of the lens. Insert a thin flat head screw driver under the long straight side of this little indicator lens, lever it outwards and upwards and towards the front of the car, it will pop out, (fitting is the reverse)

Undo the two screws that will now be visible and gently pull the cluster away from the side outwards a little and rearwards, it will pop off, its held in by brackets and metal bars.

When it's out you undo the necessary bulb anti clockwise and then the bulb itself can be removed and replaced.

Fitting is the reverse of the operation
