2001 License Plate Bulbs

How do you replace the License plate bulb on a 2001 Chevy blazer?
2 black lenses on either side of the Plate in the rear.
I can't get my hand in as there is only about 1/2" of room

You reach behind the bumper and twist the socket out of the lens.

I can't get my hand in there. there is only about 1/2" of room.

I change them all the time and I'm sure my hands are much bigger than yours!

I'll get a picture. The spare tire is under there also. I figured the lense would turn and come out on the outside.

Thanks for your help. Not sure how this works, the story behind this little light was a little funny.
