Spray some contact cleaner in the switch,1500 will give you a startling surprise at night when you hit the hi beam and nothing is there,try it,itís cheap fix
Pretty sure if it were the switch it would test bad with both the test light and the headlight would not work. Sounds to me, much more likely, it is a relay or less likely a wiring issue. Of course I have been wrong before. Flip flop the high and low beam relays to see if the problem follows??????
Worked on the "big rigs" for 45 years now just riding my Wing whenever I can. Gets cold in Wisconsin.
