These little reflectors reflect like nobody's business. I ordered the blue ones to use for my wife's license plate on her 2002 Suzuki Marauder VZ800. She likes the color and it adds a little more safety from the back. The tension from the springs help keep the wing nut from becoming loose. Just make sure you check it every now and then. The price and shipping time from Dennis Kirk is always low and fast.
would like to see a choice of colors...I received orange but was expecting red...the washers, etc. are a little cumbersome to fumble with, especially if you don't have a lot of room behind the license plate holder.
