My sisters 04 Hyundai has a frosted headlight. Is that how the vehicle was made or has the light just deteriorated. I am not talking about the external surface of the whole headlamp but of the two lamps that are inside the whole casing. The high beam light is clear but the main headlight is kinda frosted. I was just wondering if this is normal or if it needs replacement. Are there any better lighting solutions for this car?
