Removing front signal housing, DIY?
 

Looking for any info on how easy/hard it is to remove the front signal housing. I imagine it's not much more involved than replacing the bulbs? Are they held in from the front or the back?

Not that difficult. I removed them when I installed the Zeta signal lamps.

Remove the inner wheel liner enough to access the signal lamp assembly. Push the tabs holding the black molding surrounding the signal lamp assembly out from inside the bumper. You will need to apply some pressure to the black molding to push it outward. If I recall correctly, there are two 10mm nuts holding the signal lamp assembly in place. Remove those and the assembly comes out.

I did this without removing the wheels and just turning the wheels in. Plenty of room to work with. Hope this helps. Sorry I didn't take photos and just going off memory.

No that's great, are the nuts on the front side (behind the bezel)?

They are on the backside. Easily accessed behind wheel well liner.
