If you are wanting a service done you will need to specify if you are going to be sending me your headlights or if you would like me to do it with a new set of headlights. All of my work comes with a 60 day warranty anything that you purchase will come with a 30 day warranty. My work will cover any condensation that enters the headlight, faulty items that are installed (halos, led strips, pods, etc.) If any of these things happen I will pay for shipping and fix the issues that are happening with your headlights. I take pride in my work when it's somebody else's personal item so I will not cut corners and I will take my time with everything I do. I really hope nothing goes wrong but just know that if something was to happen then I will do everything to keep you satisfied. If it passes the 60 days from when you receive the item I am in no way responsible for anything to do with your headlights. If you open or modify your lights in any way before the 60 days are up then the warranty is immediately over. If you have any other questions or concerns please feel free to email me at woolzydesigns@gmail.com
