Wiring lights for Apollo 250

[stevet40]

I have a few questions about wiring. (I'm a computer guy, not a bike-expert, so these are rookie questions.)

I need front light and tail light. I purchased a front one, I'm about to buy a rear one. Do I need anything to know about these? Which ones are compatible with my Apollo 250?

This one looks the same as the one above.

This one's holes are placed different.

+ I need a harness wire.

I don't know which one. Any advice?

I guess I need the base wire + a switch for the head and the tail light, like this.
