So what do we do when we have a problem with something down the road? I have yet to install my LED taillights. If you want to keep your name untarnished, you have to leave contact info and actually contact anyone with problems back. I am not saying you have to warranty your stuff forever, you can charge money for your time doing repairs out of warranty. But that is a lot better than someone having to throw away $900 in lights (nevermind the cut up factory housing that's another $1200) because they can't get a repair done.
I'm sending you my interior set tomorrow, looking forward to getting them repaired. Please do provide contact/service/warranty info some place and actually respond to it. As I said, charge for your time. No one will have a problem with that. No one expects you to work for free for the next 5 years. Just don't leave anyone stranded.
