I thought from memory on my k5 and k10 it also worked with the park brake. Maybe the old age is setting in. I'll try grounding the valve wire and see if it comes on, Thanks for the info

The guys are right. It is only activated if you have trouble with your brake system. Look at your proportioning valve and you will see a brown wire hooked to it. That is the wire that supplies that light with a ground if there is a problem.
