Specify the wrong spring and your new stoplight switch could be ruined in no time. Too short and it will damage the switch by straining the mechanism, too long and it just won't work, or jam sideways damaging the switch itself! If you are already buying a new switch, then specifying a new spring to go with it is a sensible decision. Regular spring replacement, is a very cost effective way of maintaining that well cared for look, as springs, even Honda springs go dull with time, and a freshly plated part like this speaks volumes about the owners attention to detail!
