Good info. My notes that I have also agree w/ yours.
Map light can be interchanged w/ m-17 (8w) or L-05 (4w). I may chance the m-17 b/c even though the L-05 is supposed to be brighter than a normal 4w. I would hate dim map light. Plus for as long as you have them on (just a few minutes at a time) the M-17 should be ok.
Not having a bulb to replace the vanity sucks though.
I still need to find something that will work for that. Are you positive it is a #74? Do you have a gauge cluster bulb and the vanity beside each other to compare side by side? If I cannot find it in Polarg maybe I will try PIAA.
