Front side light unit - is it sealed?

[WalkerBW]

Hello!

I'm new to the mustang world so please be gentle

I'm looking at changing the front side lights from the nasty coloured yellow to a nice LED.
Went poking around the weekend but it looks like the unit it sealed?
I can easily take the indicator bulb off but not the one next to it, is is a sealed unit so I'm stuck with it?

2018 model with the GT500 front.
EU

TIA.
