Morning guys

I need to change my 3rd brake light on my 56 plate ST. Has anyone done this. It looks like a tricky job. I have had a a go this morning but cant seem to do it.

Any ideas?

Cheers

It tells you how to do it in the manual,
open the tailgate, remove the rubber grommets, release the clips using a flat-bladed screwdriver and remove the lamp, unclip the bulb holder and remove the bulb.
