Halo lights-which circuit

[Bill336]

As part of the upgrades to my "new old" truck, I'm replacing the crufty OEM headlight housings with new Spyder Auto projector housings with Halo lights. The question I'm pondering is about which circuit to wire them into? Spyder says "parking lights". I've seen quite a number of vehicles that appear to have them wired into an ignition circuit, so they are on all the time. I've also seen some suggestions to wire them into the headlights. At the moment, I've not wired them into anything. Insights or suggestions?

I tapped into my marker lights. They are on with the headlights at night and flash with the turn signals when the lights are off. This was not planned but I like it.
