Yes you can replace a bike flasher with a car flasher . I priced the flasher from Honda dealer they want $80.00 plus tax for it I bought a standard car flasher for $4.79 plus tax and it worked. (flasher must be three prong - Prt.#550 12 volt 20-1036-2 from Can. Tire.) I answered my own question by trying it and it worked.
