I have been searching for a guide with images on how to change the dipped H7 bulb on my 2014 Mk 3 Octavia. I have disconnected the socket for the current bulb but I can't see how to remove the bulb. I assume it has a locking collar that retains the bulb. I can be a little energetic at times and do not want to break something. Has anyone been through this and done the 'How To'?
