My friend has a 99 f-350 Powerstroke and he wants to add clearance lights to his roof to make his ford as cool as my Chevy. :) Does anyone have any pics and suggestions as to which way was easier. He is not sure if he wants to add a factory wire harness or just wire it in himself. Suggestions? Thanks.

I bought the factory lights and wire harness when I did them on my SuperDuty, there is a couple DIY articles on thedieselstop....
