Shift indicator light, brightness?

[custom10nut]

The Shift Indicator light on my tilt column is not very bright. In fact, it's barely visible, even when it's dark out. I haven't put the green filter on yet, as I wanted to make sure everything works first. There's a metal "filter" over the bulb, with a small square hole in it (I assume to keep down the glare).
How should that hole be oriented, to the right, toward the dash, or toward the steering wheel?
I'm not sure where it faces now. Am I right in thinking it needs to be to the right, so it lines up with the PRND21
