Rear view mirror map lights

I noticed the other day that the passenger side map light is out on the rear view mirror. Has anyone had to change one of these?
How do you get the bulb out of there?

There is a plate on the bottom passenger side of rear view mirror that just pops off with a small screwdriver and the bulb is accessible. 

Well I finally had time today to look at it and it was an easy fix through the lens

When my son and I replaced the bulb this summer he inserted a red filter and we liked the low level similar to the aircraft cockpits we've been in. I'm considering finding an automotive LED light that'll give the same results. Red but with a bit more output since my eyes are getting older.
