I have a 2010 silverado and i believe it has the snowplow prep package because it came with the amber cab light switch stock and does not have them. I am going to be installing the factory fog light setup (mine doesnt have fogs now and some idiot backed into my bumper end cap and the cost to fix it is enough to allow me to do a different setup... can never have enough lights!) which brings me to this question. I will be installing kc 6" apollo driving lights 100w (x2) or the kc daylighters driving lights 130w (x2) and within a year also would like to buy a single long range/ spot beam 130w daylighter regardless of what i go with and put it in between the other 2 also it prob wont matter but also a 60" led tailgate bar... I have only one battery running now and when i am driving at night and i go to use my windows you can see that intial drop cause the headlights to dim and i was just wondering if i was to go with this setup am i going to NEED a 2nd battery and then what setup should i go with from there? Ive seen people say isolator/ no isolator, i just want a setup that if i go to use all my stuff, if i use my windows it isnt gonna strain everything. it just bugs me lol.
