They are really neat! I found it to be a very well-engineered product to make your bike look cool at night and help you be seen. The lights were also very easy to install. I do think that maybe you should mention in the instructions that the lights are trimmable. I had to go to the Amazon Q & A to see whether or not the lights could be shortened. I also think that it would be nice if you also sold these lights in two packs with a reduced price, because I thought that the price was a little bit stiff for a single strand. Great product though!
