I have got a set of hid headlights and a set of spotlights from a 2006 1200. Will they fit a 2012 1200. If they dont fit how much are they worth i brought them off the board but cant remember how much i paid .
If the ballast units for the HIDs came with a mount bracket, then the bracket probably won't fit as they changed the front subframe when they changed the side panel design.
If however they are just the burners (bulbs) and ballasts then they will fit any model, but you will have to get creative with mounting the ballasts.
If they are the Hid50 set from Les then they will fit in the new bike.
My set from my 2005 bike fitted the 2010 bike with the only "issue" being that the oil cooled is moved slightly forward and didn't allow me to fit the Reyno oil cooler guard that I bought.
It would have fitted but I didn't want to risk damaging the paint on the back edge of the beak with chafing.
Hope this help but you really need to be more specific about what you actually bought and want to fit.
