Hello I’m new to plowing and I have an 05 Ford F-250 with a Meyer 8’ plow with wings. So we have replaced both the light control boxes to the new universal Meyer ones and we still have issues with the plow lights only. The truck lights work fine. The drivers side plow light is very dim on low beam and the passenger is normal. Then on high beam, the passenger almost goes out completely while the drivers side brightens to normal. I have taken apart the whole wiring harness and cannot find any issues as far as connections or corrosion or broken wires. The plow light switch has a 3 pole lighted switch in the cab which seems to be working good. Any help would be appreciated, thanks.
