Headlights had an issue in the early years with some allowing water inside them. Whatever the cause Chrysler came up with a kit that was said to prevent it.
The kit had two large rubber covers that replaced one of the covers on each headlight, these covers had a membrane on them that allow air to pass through but not moisture, there were four pugs to replace the existing grey vents.
The photo shows what was supplied for one headlight assembly and what was replaced, these kits are no longer available.
