I just sent you a PM, but seems as though you found what you were looking for. Once loaded, they will show up all the time, and depending on the settings you have may or may not make a beep sound when approaching the lights. The pop-up window will show up even when not viewing the nav screen, like if you have up the radio screen or xm. The popup will come on normally a few hundred feet before the light and go away just after you pass it.
