Mick, I can't remember about the sidleflight bulbs, but I knwo when I replaced the indicators, you can do without removing anything with some time, effort and patience!
But I just undid the bolt at the back of the headlight, holding it in..... (you see when you open bonnet)...... then did it that way as gave a bit of play....
So assuming it would be same, but someone will confirm I'm sure
