Why is it after every plow install the mfg. disables the headlights when operating the plow? The plow lights aren't really worth two cents. IMO, they are no better than the under the bumper type driving lights you see on cars! If I really want to see whats ahead of me I need to install some highlights or follow the wiring diagram so I can pull the wire to have both plow and headlights to work simultaneously.
