I just installed a new harley billet headlamp on my 03 duece,everything went great until i tried it out .To me it seems like the high and low beam are swithed. I checked the wiring diagram in the service manual and everything is in the right place(colors match up ). Has anyone ever ran across this ? I thought about the white and yellow wires(those should be the high and low beam) but thought i would check and see what you guys think?

 

Happened to me once, I just rewired until I got it right. Wierd though.

 

I just switched the white and yellow and it fixed the problem. It must be wired wrong in the headlight shell.
