I think you need to provide a little more info on what you are selling. Generally in the mod community if it uses all OEM parts, someone releases a DIY and then offers a kit for the people that are not so inclined to do it themselves (which is usually the majority). If it is just a leveling switch and some harnesses with a few resistors then I think your price is a bit steep but for all I know you had to come up with something a little more advanced. Rest assured that there are not 100s of people out there who are going to 'steal' your idea. Have you proven it on vehicles other than yours? It's not like you are going to make millions selling leveling kits for aftermarket VW headlights. That said, we all respect an individuals hard work and would want to reward them. I just think you should be a little more transparent about what you are selling and how you achieved your result.
