Claim:
A method comprising: clearing snow from a surface using at least two snow plows plowing simultaneously, wherein each snow plow has a plow blade; both of the at least two snow plows driving in substantially the same direction wherein a first one of the at least two snow plows is driving behind of a second one of the at least two snow plows; the first snow plow having its plow blade oriented to plow snow toward a first lateral side of the surface being plowed; the second snow plow also having its plow blade oriented to plow snow to the first lateral side of the surface being plowed; the first snow plow being driven in a laterally offset alignment with the second snow plow such that the plow blade of the first snow plow catches snow plowed toward the first lateral side by the second snow plow and further plows at least the caught snow toward the first lateral side; at least the second snow plow having at least one electroluminescent (EL) illuminated surface mounted thereon so as to be visible to a driver of the first snow plow; and the driver of the first snow plow using the EL illuminated surface mounted on the second snow plow to maintain the laterally offset alignment.
