You should look into the Explorer visor swap. They've got lighted mirrors on the inside and they're like double visors. Meaning you can have a visor on the side window AND in front of you. Might be something to take a look into.
And they're somewhat plentiful and most of the ones you'll find are the light grey of your headliner already. For people like me that have dark grey headliner, they're kind of a pain in the butt to find in dark grey. So much of a pain in the butt, I've never seen a set in person....and I'm a regualar everyday junkyard hunter! lol.
