Unfortunatly for you, the age or your car takes precedence over the mileage. everything in the link should be done.
https://congletonservice.com/service-schedule/LR4.pdf
its pretty much like any other car.
oil change. do it every 5-7.5k rather than 15k miles.
cabin filter 1x per year
engine filters every 60-75k.
replace brake fluid every 2-3 years.
replace spark plugs at 100k.
replace engine coolant every 80-100k.
replace belts at 100k. schedule says 150k, but that seems like a lot to me. better safe than sorry and do it early.
fuel filter is a 10year part. but requires tank drop to do. id skip it unless your having fueling issues.
BG44k fuel system cleaner 1x per year. do not skip this. it actually makes a difference, and could alleviate the need for fuel filter replacement.
replace transfer case and diff fluid every 60-75k miles.
replace trans fluid and filter every 10 years. replace it with a 2pc pan/filter. the original pan has the filter built in and requires ALOT of work to install. the 2pc kit can be slid in place without other parts removal.
a very odd item in the service schedule is flexible brake line replacement every 6 years. this is kind of an annoying job to do. if your brake lines are good, show no bubbles, cracks, etc...just clean them up and use a dressing on them to keep them from drying out.
the bulb your looking for is miniature wedge # 2825. this is the bulb type, not the land rover part number. you can pick it up at any parts store.
