The headlights are completely inadequate. If you are taking a turn at night, the lights continue to stay straight with the direction of the vehicle instead of following the vehicle so that you end up taking a turn blindly and cannot see the curb or edge of the road. It is a totally unsafe situation. We have found that you may have a bit more visibility if you run with the fog lights on, but very little improvement. Please find a solution, additional headlight, as this truck is very scary to drive at night.
