He everybody, I need your help.
I'm am a student at the Technical University of Delft and I'm studying Industrial Design. I need to know a few things about bike lights and especially the requirements for them that people have in the States. In the end I have to come up with a new concept for a Dutch company that wants to introduce themselves in the USA. So can you help me by maybe answering a few of these questions:

What type of lights do you use? (detachable?) and why?

Where do you use them for? (to see or be seen?)

What do you expect in terms of lifetime?

What do you think is a good idea for bike lighting?

Maybe some other stuff that's on your mind?

Those are my questions and I would like to thank you in advance for helping me out!
