The headlights and high beams are dim . When the high beams are on other cars oncoming are not affected as they never flash their lights because my high beams seem as though they are just headlights. Also the fact that the high beams shine like headlights, there is no option for brighter lighting which makes it hard to see far ahead. I live in a rural location off of a narrow highway with down slopes with water at the bottom on both sides of the highway where large wildlife such as deer are plentiful . Insufficient high beam lighting imposes unsafe travel conditions since the headlights are dim and the high beams are how the headlights should be leaving no option for brighter visibility. I noticed the lighting being dim years ago but I thought it was just something to do with my trucks lighting until I began searching online again for a remedy and found many other owners of the same year make and model with exactly the same issue. Therefore in conclusion perhaps is a manufacturer defect. My truck is the most reliable vehicle I have ever owned, it still runs great, I keep it well maintained and I intend to keep using it for as long as we both shall live. I am [XXX] and obviously my truck is over 20 years old and runs great, it would be terribly upsetting if an accident were to occur due to insufficient exterior lighting. I cannot remember exactly what it was I had previously contacted NHTSA regarding my truck , though the exterior lighting is of greater concern now. I noticed the dimness of the exterior lighting since I have been living in this location a lot because there are no street lights along the freeway nor highway as opposed to where I lived prior. Thank you very much for giving me the opportunity to express my concerns as I appreciate your time and consideration in this matter.
