Used indicator switch (Part Number #XPB101290).
I suspect it's original to the truck. Works fine, but it has a slight wobble. Previous owner bought a new one and I've been sitting on the new part for a while. I just swapped my steering wheel and I'm not sure I want to do that again in a hurry, so replaced this working switch with new part while I had wheel off.
The only other weird thing I noticed is that after I installed the new one the green 'lights are on' indicator on the dash comes on. I'd never seen this light before, so I suspect this switch doesn't cause that to light. High-beam, blinkers, horn etc all work just dandy.
No idea what it's worth.
RN has it listed for a ridiculous $269 (http://www.roversnorth.com/store/p-6...der-90110.aspx
