2012 Peterbilt 389 Lighting problems

At night when the pavement is wet from rain, snow or mist, you lose sight of the road. The light coming from the headlights fail to shine up the road. It is very easy to drive beyond the capabilities of the lights as it absorbed by the moisture. You cant see anything, pot holes, the lines, debris , nothing. I have tried using the high beams and the is not any improvement. I have found that the only way a driver is able to see the road is to keep the head lights on dim and to turn on the spot beams with them aimed directly in front on the truck. I have pictures to show what I am talking about. *Tr
