Yes, they fit although the intended lenses spread the light better IMHO. You could use the fluted halogen style ones I suppose. Also be careful about getting ones with good gaskets, they matter because the 700s have slightly different condensation dissipation design (hole in the lighthead vs slit in lens (this changed over the years too). I replaced the red/white max / side beam strobes on a rescue with solid red 700 halogen lenses and it worked fine and got rid of the white to the rear.
