Why do some headlights have bits of plastic protruding out of them? I was cleaning off the headlights to my car the other day after another couple inches of snow fell, and I started wondering about this. Are they just there to mess up my ice chipping?
My sister says they’re there to mark where the lights are in case it snows. I have my doubts about this for several reasons. 1) Any decent amount of snow will cover these little 1/4 inch deals. 2) How many people can’t find their headlights, seeing as (with the exception of a few classic cars that aren’t typically left out in the snow) most cars have their headlights at the outer edge of the car, not the hardest thing to find. 3) She tends to use alternative medicines to ease her mind, if ya know what I mean.
Anyways, I can’t see the auto companies spending the extra 1/100000000th of plastic on these nubs. My WAG’s are that they either have something to do with stress relief in case a rock hits them, or more likely, they are simply there so the robotic arms can line up the headlights when they are installed.
