My system is switched on and off through the OEM (or, rather JDM) wiring harness that the Zstore sells (a relay was also needed in the install; bigaudiofanat helped me do it). A couple of members here have seen my fog/brake light in person and have remarked about how effective the flashing is, especially at night.

I've also drove with it on while in front of cops and other law enforcement officials and have not been pulled over for it; the legality here is kind of iffy - you can only have 'X' amount of flashes in succession, but the new Mustang turn signals are sequential brake light flashes, so...? If you could produce such a dynamic system for the Z, I'd be more than willing to buy/test one from you.
