bryanj im not sure what you are talking about. The right side assembly has the headlight switch to turn off my headlight, but I dont think the starter button turns the headlight off. I turn my headlight on in the daytime, and I can start my motorcycle by putting an o-ring pick into the hole, but Im not sure if it turns the headlight off. Not sure what you are meaning...I am just missing the black button, spring (which I may have one that will work with what I had sent to me this week) and the brass post...thanks
