@ S8yot- it's relatively painless you may be able to remove the glass in situ just need tro remove the trim below the lights & the indicator PFL. But just take out the light is what I'd do and try to buff up the 150k miles glass at the same time.
the seal is around £7 from the dealers took them 2days to get them in.
Under the headlights you say Botang; hmm... some photochopping is in order me thinks. I've found the bigger 10mm leds as well 6 in a row.
