    I purchaed replacement lights for my 2005 810 and 2006 8611 plows. When new lights installed and plugged into truck wire harness. when i flip light switch on blizzard control the plow lights did not work and the truck bright lights were on. Signal lights icon on dash was lit up as well. is this a relay problem or are replacement blizzard lights different?

    thanks.

    Old plow lights did work perfectly...replaced due to age and hitting too many curbs broke black plastic housing. Parking lights work in old and new plow lights. New Plow lights installed are Blizzard Plow Lights. Relay went bad?:confused:

    I would check for pwr at the grill plugs first. Assuming that you did plug in the one wire plug at the controller. I believe that wire grounds out the relays for the lights?

    Are the replacement one exactly the same? 6 pin connector?

    Old ones were likely 5pin. May need a ground fixed

    Yes 5 pins used but a 6 pin connector. But new ones not working and old ones did? Unless they are dd lights then they might be different.
