Using leds as voltage indicators

This project will be the death of me (old age) its taking so long!

I have a couple of solid state controlers which I plan on installing in the same box as light dimmers for two sets of 7, series connected lamps.

What I wanted to do is also install a row of leds for each controller to indicate average voltage to the lamps. I want the leds because they will align with a printed color temp chart for quick reference.

How do I get an led to light at the correct voltage?

I want to indicate average voltage between 10V and 16V in .5V increments.

Thanks for your help, I know this must be a stupid question.
