Fitted...
The IR beam is offset slightly to the right, and the LED shines from the upper left corner to the lower right corner for maximum light distribution.
I experimented with several different set ups and settled on this because when I put my hand in the cubby, I don't want my hand to block the light and I want to be able to see into it as well.
So, with my hand off to the right the light coming from the left, this allows me to activate the light while still having a clear view of what's inside
The light doesn't show up well here, but I'll get some good pics when I put it back in.
