It's not scary, really.

Lose the cover (that's another four screws) then you'll find four holding the h/lamp to the pop-up frame.

I removed the front two, loosened the rear two and flipped the headlamp up, sort of like a tipper truck.

It gave me plenty of room.

I think I used a plumber's water pump wrench to loosen the side light connector, as it was a bit hard to get sufficient finger purchase on it.
