Fazer 1000 high beam issue

[Tommy666]

Hello I have a problem with my Fazer and wonder if anyone can help me out, the lights are permanently on with no switch provided to turn them off , when I start the bike and use either the flasher or high beam switch the rev counter drops briefly to zero and all the warning lights on the dash illuminate for a couple of seconds then normality is returned, however it only performs this unusual trick on first using the flash/dip switch ?‍♂️ I have never noticed this issue until I took it for the MOT and the tester pointed it out to me , I should say the bike passed its test as all lights work normally, a mate has the same bike and has the same problem, hopefully someone will have had this issue and found the solution
Regards Ian
