The Yelow Top is for Deep Cycling & Cranking, the Red Top is for Automotive Starting and the Blue Top is for Marine & RV Applications.

I went with yellow due to the winch and off road lights, I think red would be perfect for a stock vehicle but would recommend yellow or blue for any built up off road vehicle with accessories.
