Default coil pack arc

I have a 99 ranger 2wd 2.5 L with 177,000 on it. While the engine was running, I noticed an arc and it looks like its coming from the coil pack. Its #1,2,3,4 pass side. I have always had cars with dist caps, this is my first with these coil packs. Its actually made a small burn mark in the plastic housing. Can anyone explain this electical system ? Should I replace the power pack module ? I think their original spark plug wires. thanks

Yes replace the coil pack.

Very simple to do just 4 screws holing it down.
