Are these the ones your talking about?

I did not install the load thingy in mine cause they worked with the factory flasher,alltho they do flash about twuce as fast as stock, but i like that.. Now if you plan on making the rear LED you will need a low voltage flasher, or put some kind of restior in line in order ot trip the factory flasher.. The cool thing aobut the Mirrors is you can wire them to be used as running lights also..
