Hello John, In addition to 687hug's post:- I had the delightful experience of changing the onside (drivers side) dipped beam bulb. Mine is the " ordinary" TS type bulb. I would certainly buy a few spare poppers that secures the wheel arch liner. The patience of a saint may salvage the old ones. Small hands may help. Mine are not large it still was a struggle. As I remember, I think you can change the onside bulb from under the bonnet with a little careful aerobics. David.
