They have been out for quite a while now. There are basically 2 uses: to simply protect your headlights, or to be used in conjunction with The Mask styling kits. These kits have patterns and when you paint with them, they can look like projectors or any shape you like. The kit costs about another $15. Never seen them plain on a car though.
Ok why is it the same model for 98-01? I thought the lights were enough of a different shape between 98-99 and 00-01 that one universal thing wouldn't fit? I'm asking because this means the difference between me having to make 2 molds as opposed to one for the eyelids I'm doing.
