So just installed mine, drivers side is perfect no issues.
Then I decided it might be a good idea to document the install to make it easier for others.
As bpd1151 stated start by putting both mirrors in the full up position.
Position prying device in the clip towards to front of the vehicle.

Then gently pull this area down slightly

Then push in from inside behind the mirror on the other clip, you cannot see this from under the mirror.

The light will then fall down.

I chose to slightly re-crimp the push on terminals and apply some dielectric grease

Then push back in place and enjoy.

But then........the passenger side only lights up red.
SMH.........
