Okay, I think I know what you mean but for clarification are you referring to the High Beam light indicator on the dash? I believe it is a blue colour. Does it stay on no matter which position the switch is in? Have you tried playing with the hi beam/turn signal lever a few times to see if it will turn off. If not perhaps the issue is with the lever as suggest by orangesoda123. This problem has not been posted about before.
