Headlights were about as bright as a candle while using high beams changed the bulbs and used a head light restoration kit and within a week headlight lenses were hazed over again high beams are no brighter than low beams.
I live in the mountains of tehachapi, cannot see a thing when driving the mountain roads. Maybe 40-50 feet in front of the truck nothing to the side. Making a turn is like almost driving without lights.
Head lights are so poor when driving in rural areas and poorly lit areas that the lateral lighting is so poor that you are left to guessing where and what you are turning into, extremely dangerous to all, dealer where purchased new stats there is no fix, accident waiting to happen.
