I went out to change the blown lamp in the headlight today --- of course it was the RH one again, which is less accessible because of the filling tube for the windscreen washer.
I took the old one out, thinking to myself, why the heck can't they make this easier to get into? Just making the filling tube fold out of the way would help. Grumble grumble. Especially since there are 2 points on the tube that look like the joints in bendy straws. Hey, does that clip move? (You can see where this is going.)
Anyway, yes, the filling tube can be unclipped & folded out of the way, & it makes putting everything back together a lot easier. I wish I'd discovered this years ago. Next time, I'll find out how much easier it makes removing the blown lamp too.
