Hiya, Ian. Welcome to the community.

Is your problem removing the boot from the dash or the bulb from the rubber boot?
If the former, remove the dash (3 allen head bolts), get your nails under the lens surround and then ease the boot to one side. Should just pop off.
If the latter, just roll the rubber boot down until the bulb is exposed. Grab the bulb and pull/wiggle (gently) until it's free. It is difficult to grab but can be done. Whilst you're there, replace the bulbs (except hi-beam) with 10mm wedge LED's; easier to see in the sun.
Hope this helps.
