Many 4x4s started receiving plastic headlights in the ’80s. Over time the plastic lights just didn’t live up to their glass predecessors. They allowed OEMs to build more unusual and aerodynamic grilles and light assemblies. They were better at projecting light than the basic round or square bulbs previously available. Unfortunately, the plastic faded out over time, reducing light projection and looking miserable to boot.
We tried out a Sylvania Headlight Restoration Kit to see if we could bring old lights back into the bright. The results were enlightening.
