Before leaving for Snowdonia I wanted to get my head light fixed. After taking another closer look and having bought the necessary tools (torx Allen wrenches) I realized that I didn’t actually have to take off the front cover with the glass to access the bulbs like I had assumed:

Instead there is an easy access lid at he back of the casing. So on the way up to Snowdonia I stopped at Halfords (Forstinger in Austria), got a new bulb and installed it.

And there was light and it was good … knowing that I could use the high beam for it’s actual purpose again.
