Volvo V60 High level brake light
 

Hi all,
I have a 2012 V60 & just spotted my high level brake light is not working, I contacted my local dealer & was informed that it's a sealed unit so I've ordered a replacement but have been told that it will take 1 hour to change the unit. Has anyone attempted this & if so I would appreciate some advice / instruction on how to do it. I removed the plastic panel from the inside at the top of the tailgate & it looks like the tailgate spoiler needs to be removed.

Thanks, any help received would be appreciated.

Presume you have checked for power at the light ?
