It works, but it does pop out on its own, on occasion. Almost busted my mirror and my windshield a few times.
Hard to install due to where they have to be bolted down but it works very well.
Great product, easy installation. Alex did a great job with answering all of my questions and also getting this product shipped to us.
SO it works great, the only down side is that I have a newer car and there is not a gasket for that style turn signal they did include a flat piece so I could make my own which works. -easy to use and now other drivers see what I am doing..
Doesn't work in 07 honda crv. Rest of kit works perfectly.
