Changing rear light bulb on Skoda Fabia 2018 

Just another Wintry Thursday night in an Scioból, Men's Shed in Gaoth Dobhair, checking out a rear light fault on a Skoda Fabia 2018 model. Note the random nature of the fault coming fro m a poor contact. Need to look at more consistent lighting on detailed elements.
Hopefully might assist someone else.
