haha yeah same I looked at it and at first looked at prising the whole thing off the roof! then realised that the clear part probably comes off - low and behold it did!



Lol, when I changed mine a couple of years ago I thought exactly the same. Unfortunately for me I realised about the plastic cover after first attempting to undo the whole thing and knocking the earth wire out. I just cheekily popped into the dealership the next day and said that the interior light had stopped working, so they sorted it for free without me having to fiddle about with it.
