What is the best lens type for a Nissan Pathfinder headlight?
Answer: The quality of the headlight lens is determined by its ability to withstand ultraviolet rays and breaking. Manufacturers use a polycarbonate lens because it is easy to mold, but the downside is that this lens material is susceptible to UV rays and scratches. The other type of material is called polymethyl methacrylate or PMMA, which is UV-resistant; however, its brittleness makes it a bit difficult to maintain. The good thing with today's headlight lenses is that they can be strengthened with the use of chemicals. To make a polycarbonate lens stay clear longer despite exposure to UV rays, a coating of UV inhibitor is applied. Likewise, a silicone hardcoat makes these lenses more resistant to scratches. For PMMA lenses, the brittleness is eliminated by adding plasticizers in one part of the manufacturing process.
What should be done to make a headlight for a Nissan Pathfinder road-legal?
Answer: The Land Transportation Authority enforces the Road Traffic Rules set for all automotive headlights. The standards indicate that all headlight bulbs must produce visible light, with as less yellow light as possible. This ensures that a wider part of the road is illuminated brightly especially when driving at night. A thousand feet of illuminated distance from the car is required for the bulb to pass the testing. Also, there has to be a definite upper beam and low beam intensity for the bulbs. For Type 1 lights, the upper-beam intensity must be between 18,000 and 60,000 candela per lamp, while the upper beam value for Type 2 lights is from 20,000 to 75,000 candela per lamp. Other factors that drivers must check are the proper alignment of the headlight with the vehicle body for glare prevention as well as the correct bulb wattage that is approved by the manufacturer.
When is it time to replace a Nissan Pathfinder headlight?
Answer: It is time to replace a Nissan Pathfinder headlight once the light bulb starts to burn out and when the lenses begin to discolor due to exposure to UV rays. A discolored headlight lens will be less efficient in reflecting light, while a burned out bulb just hopelessly needs replacement. Immediate replacement of these components is necessary in order to prevent being pulled over by traffic enforcers.
