They will handle an H4 bulb up to an 80/100 watt off road cause that is all I have ever used and still do .


Most of us only have a taillight and headlight so what extra load is there ? You running heated grips and seat ??????? They worked fine in stock bikes when you had signals and signal beepers and all the dash lights as well as some that were fine with driving lights . Maybe battery size ? But I am suspicious of the tach cause it has happened twice now . Guess they all get a speedo from now on . Thanks .Red
