got same problem right now and pretty sure its only a PNP switch thats needs to be replaced. my arrow was also flashing but after i cleaned the battery terminals and reconnected them it seems to go away... i'm gonig to do PNP switch this weekend ill let you know.

Pull your lights switch out and disconnect the plug.
Find Green/Red wire which will be #5 on the plug and cut it.




Results after I cut the wire
