Yes. They come with good quality 3M tape on the back. Since they are so light, I don't think there will be any problem with them staying "stuck on". Will have to see how the tape stands up to water/rain/snow.Do the LED strips just stick to the window?
I had the choice of sticking them to the glass, OR to the adjacent black plastic trim piece. I decided the glass would be better. It places the strip at a slight angle which makes it slightly brighter to vehicles that are not directly behind my car. Also, if I ever decide to remove them, it can be done without any residual damage to the underlying surface.
