Removing Headlight Knob/Switch?

[Ludington1]

Hi, new here learning about my 70 Blazer. I was looking at taking out the dash bezel to clean it up a bit. On the wiper control knob, there is a tiny flathead knob holding it in place. However, it doesn't appear to be quite so obvious on how to take off the one for the headlights?

I didn't look at it very long, so maybe it IS obvious, but thought I could ask here and save some time.

Thanks in advance!
