resetting the combination valve brake warning light

After I installed a new master brake cylinder on my 1979 jeep I bled the brakes without locking the valve and now the warning lamp is on all the time. What do I have to do to reset the valve and turn the warning lamp off? The brake system is non powered.

When I replaced the rear pads, and bled the brakes, I ran into the same issue. I didn't do anything with the prop valve when I bled them even though it seems like its about 50/50 on this forum as far as the pin on the valve. My light was on also after bleeding, and it just took another round of bleeding to have it go out. There was still air in the line after the first bleeding. Try to rebleed them.

That normally means you still have air in the lines. The switch is self resetting on the ones I have seen.

Try bleeding in this order. RF LF RR LR RF LF. I read somewhere that doing the fronts first is supposed to set the prop valve. Worked for me.
