2006 W900 lights are haunted. Help!!!

[Grumpyjoewv]

I have an 06 W900. It’s an earlier year model with the 2005 style dash and toggle switches. All of the following issues have started in the last couple of days and at approximately the same time. All four headlight bulbs were LED. Well the passenger side low beam bulb died so I just popped in a halogen. Then not long after, the driver’s side low beam started strobing. It would do it for a while and then straighten up and start again. So I pulled it out and replaced it with a halogen as well. The two high beam bulbs are still LED because I rarely use the high beams. Now the fun begins. I have no trailer brake lights at all. Tractor brake lights are fine. I used a test light starting at the pigtail and made it all the way to the fuse box. There is no power at all to the trailer stop lamp fuse. Next, my overhead ABS light started flashing on and off. It’ll do it for a while and stop for a while. When I turn my headlight switch or marker light switch on, I hear a relay clicking somewhere in the center of the dash. I’m guessing it’s the turn signal stalk? Maybe? My dash indicator for the right turn signal also comes on at this time. The flashers and turn signals still seem to work fine. When the headlights and marker lights are off, I can turn the flashers on and almost all of my gauge and switch lights flash with them. The switch and gauge lights quit flashing when I turn the headlight or marker switch on. I’m sure it’s something totally simple. Would the halogen headlight bulbs be a possible cause since the high beams are leds? Please help!!!!
