That is why on the packages of the lens covers and such has to state. Not D.O.T. approved! Not for on Highway use. For off road and show only. But that is what the fine print says if you take the time to read it. Why is that? It's to give the others around you an chance to know what you are doing! As far as I am concerned it tells me a person that does this could careless about others around them and are not very considerate and probably don't use their turn signals and don't pay much attention to the lines on the road because they think they are just there to look pretty and just for decoration. One thing for sure If I was a LEO I would pop every vehicle I saw with such done to it. Can you tell I'm sick and tired of idiots that cover their lights so you can't see them, Install super bright lighting systems then don't have them aimed properly. I just pretty tired of stupidity! If you don't like your lights TUFF! Your not driving a show car! If you are showing it fine put them on during the show but just give others half a chance not to run over you or hurt somebody! We have to live together it not always about you! Generally speaking! :rant:
