My guess is it will not. A typical flasher uses a bi-metal spring/contact to make and break the circuit which results in the 'flash'.
I believe if you half the voltage then you double the current, and this is what triggers the bi-metal spring...current flow in the form of heat!
If the flasher did work, it would be at warp speed, just like when you hook a trailer up to your lighting system and don't consider the extra load and install a HD flasher...I may be wrong about this though.
