Top break light

its held by clips - open the tailgate - you will see some blanking plugs - remove these then use a screw driver to press the clips and pull the lamp out - disconnect the washer jet pipe and connector - then change the bulbs...assuming they are blown
 
i thought the high level break light would be LED and one complete unit?
 
looked on the pdf for lights and it shows 3 bulbs....

doesn't the gt spoiler have a specific hatch/boot panel?
