illuminate switch when headlights are on

I have a 1985 John Deere 850 tractor. I am trying to set up a new set of led flood lights on it. I am trying to use an illuminated switch. I would like this switch to light up when the headlights are turned on. I want the switch to have the constant ability to power the flood lights but only illuminate the switch itself when the headlights are on.

oh and here is the switch i want to use

The bulb or LED is merely connected to the output (ie, the switched +12V to the light/relay) with its other end to GND.

that will make the switch illuminate when pressed from my understanding

that is the same wiring scheme.

Correct.

what i am trying to do is make the switch light up independently of being pressed. i want it to light up when the dash lights come on. in other words when the headlights are on i want it illuminated but dark during the day when the headlights are off. i dont need it lit up when pressed as the flood lights will be enough indication of that. thanks

Well now that you have clarified which lights... NO1 goes to whatever you are turning on. + is the LED/indicator +ve. Connect that to whatever you want to light the switch.

awesome!!!! thank you greatly. i know i am making a simple install into a pain but i cant do simple on anything for some reason

IMO that switch is not that simple. I wish I had that diagram else that pic of its base (with the + & - for its LED) last week when I dealt with a stumped poster. And better safe than sorry - you do NOT want to inadvertently switch +12V to GND. That's one of the dangers with illuminated switches, and any switch that has both +ve (12V) and GND connections. But that switch is good in that its indicator is independent of the switch terminals so it can be wired to anything. And as I often say, "simple" does not mean "not tricky". Best wishes.
