You've set me thinking.
My 16 Impreza has similar climate control knobs. In the dark (with the lights on) it's easy to see where the dials are set but in daylight, the little LED cannot be seen. I'd suggest making a very visual pointer so you know where it's pointed.
I miss my legacy with the automatic climate control. We had to tweak the temperature occasionally, but now we're constantly adjusting temp, amount of wind and direction. I miss my Legacy.
