Removing front indicators

I want to change the seals on my front indicators. I have pulled the lenses off and its not clear how to get the lamp out. I've looked in the workshop manuals and had a search on here with no luck. Can't be too hard can it?????

 

Drill out the 2 pop rivets

 

Whs^ then refit with self tappers

 

Thanks davidoft and andyv. Thought it was those but thought I would check first.
