Head lights are not working

[Xonair]

The last time I was at my camp I noticed that my head lights would not work correctly. One of the amber lights would come on and the head lamps would be really low and flicker like an old horror movie scene. The tail lights would come on with no problems. The one thing I did notice is that both the front and rear lights would come on with the key in the off position and the FNR in the N positon. Before the lights only worked in the F and R position. Question is, Do you think the switch is bad or is their something more deeply rooted?
