The short answer
NHTSA received Mack Trucks, Inc.’s report on Oct 30, 2018. Copied from NHTSA on Oct 19, 2026.
Every line below is in NHTSA’s own words, with its source beside it.
What’s wrong with it?
The driver may operate the vehicle with the snow plow headlights on but the marker and tail lamps off, reducing the vehicle’s visibility and increasing the risk of a crash.
Mack Trucks, Inc.
(Mack) is recalling certain 2019 Mack Granite (GU) vehicles equipped with snow plow lamp preparation kits.
The snow plow headlights can be turned on without other exterior lights, and high beam indicator will not work when the snow plow high beams are on.
As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, “Lamps, Reflective Devices, and Associated Equipment.”
