What wire gives power to my headlights?

[Defend74]

I'm not very mechanically inclined but I'm attempting to install a new grille with amber lights that I want to wire into the headlights so they run at the same time. When I look at the headlights, there is a black wire, and then 2 others with green and blue stripes respectively. Which one of those wires should I use to connect the red from my grille? I'm working on a 2014 ram 3500.

I'd tap them into the parking lights. So they can be on with just parking lights or with headlights

Thank you that was a good suggestion. I got it done.
