Hey,
I've not done it but from what I'm aware, if it's like most cars and specifically the 6L
Ibiza, it's bumper off to remove the headlights, then when I've seen people modding their front lights, they actually put them in the oven for the bond between the body and plastic to soften up, you then need the right type of tape to rebond them together. Not a quick or easy job really
Mine could do with sorting but they're not terrible so I'll leave it a while.
