how do I change turn signal bulb in pass. side mirror head?

[mccullor]

I have a turn signal bulb on the passenger side that isn't working in the mirror head. How do I change this, does the small plastic piece pop out, I don't want to break it just fix it. I hope I don't need to change the mirror just to replace a bulb. 2011 Dodge Dually with the fold up mirrors.

Those are LEDs, I don't know if they are serviceable, you may have to by the assembly.
