Exterior Lighting

I'm looking at adding a few exterior LED lights across the bottom of the old Dodge. I noticed that there were lights with one wire and a post that grounds off the truck. The second type had two wires, power and ground. Pros and cons of each?? Thanks for the help.

Jamie I think the most LED's have 2 wires to the white being a ground

Really no pros or cons as long as what you are mounting it to is grounded to the pickup. I prefer having a ground and positive wire. Simply grounding the ground to the frame at the nearest point available.
