I have an 06, 2500 w/Meyers plow and head light issues , the dealer mentioned that sometimes the timp will not recognize the plow lights therefore no no lights , my hi and low beams on the truck and plow work most of the time but sometimes switching from hi to low or low to hi = darkness until I hit the hi low switch again, I am at a loss as to whats wromg but that dealer plow scenerio seems questionable, the TIMP is 800 and change.......
