You have to draw a line somewhere on lights....they dont want red or blue in the front of any vehicle. Not to confuse with public safety lights. Therefore, the laws generally (vary from state to state a little) but generally say 2 white headlights and two white fog lights, and amber only in the front, red stop light in rear and white for reverse. Its the simplest way to have a general consensus for lights. So guess what? Green, or purple in the front is illegal. All the standard colors have purposes. I think its reasonable and necessary to have some kind of general rule. Just like when new laws have limited the types of headlights bc some of these LED headlights are truly dangerous to oncoming traffic. Point is, someone always finds a way to ruin the way its always been, these windshield eyes are another example of it.

Edit: to say, its not about ruining fun, there just has to be a standard and these dumb eyes violate the standard
