Meyer Headlight Adapter 07777 (Nite Saber Lights - 2014 & up GM Trucks) This is required to prevent the vehicle Body Control Module from turning the headlight circuit off when switching from vehicle lights to plow lights. Works with Nite Saber and Nite Saber II Lights ONLY.
In addition to this 07777 kit you will need (2) Module C Harnesses (M07118). Click on the Related Products tab.
Per Meyer Service Bulletin 247R1: "Due to changes made by GM on the 2014-2015 (1500) and 2015 (2500/3500) lighting system, prior to the activation
of the Meyer Controller or the Meyer Plow Light Switch the GM Head lamp Switch must be in the “OFF” position.
This is also true when switching lighting back and forth between “Vehicle to Snowplow” and “Snowplow to Vehicle”.
If this is not followed the vehicle BCM deactivates the output driver for the low beam circuit and headlights will not
work on the vehicle or the Plow. The vehicle ignition switch will need to be cycled off and then on again to reset.
Meyer Products is pleased to announce we have designed a new module for these vehicles which will eliminate
the need to use the on/off sequence for snow plow lighting as stated above. The new adapter kit part no. 07777
contains a vehicle adapter set and 2 modules. The modules are sold separately as part no. 07776. The adapter is
not sold separately. The modules have a distinctive cover which is blue/green in color instead of yellow. These new
modules are only recommended to be used on 2014 & newer GM vehicles. It is important that the
(2) red wires, with 5 amp fuse each, of the adapter “B” harness be connected to the positive post of the vehicle
battery. DO NOT connect both red wires together and attach to the positive post of the vehicle battery with
a single 5 amp fuse. During the process of turning on/off the plow lights, the plow light and vehicle lights are
being initially powered with the red wires with 5 amp fuses. During switching of lights from plow to vehicle or
vehicle to plow both vehicle and plow lights will be on for a couple seconds which is normal operation for the new
