Ok, I give up - what's needed to release rear turn signal light stem/holder/support?

Left side, the one I need to get off the bike. I think there's supposed to be a cover on the hole; bike didn't have any. It appears to be messed up a bit in there. I can't take credit for that. I'm guessing a PO got impatient and used brute strength and ignorance:

Right (as opposed to wrong?) side:

HALLELUJAH!

I went out in the garage and stared at the whole setup. Noticed the wires that run inside the support and into the under fender area. Saw a bolt that was in the same general aarea as the wires. Took out the bolt, figuring if it's the wrong one, I can put it back.
It's the correct one and the support is now sitting on the floor (after unplluging the two wires from the harness under the fender.)

Thanks to all of you for your stepping up to help. I'm not out of the woods yet, but I'll see if I can remove the bolts for the footrest carrier/support now or if I'll need to remove the whole Tupperware. Not HUGE endeavor there, but I prefer doing the work that's required and not any more.

Thanks!

These are lower half where the saddle bag brackets attach with 1/4 turn bolts in the brackets using the special tool believe bolts stay with brackets, sorry inability to inspect at moment.
