How does it work?

Using diagnostic signals the module tells the vehicle to activate the respective lights. The module does not rewrite computer code or affect the vehicle. The codes are the same that the dealer could use to diagnose your vehicle.

Will this burn my computer?

The module does not put out any voltage and will not burn up the computer. It’s much like plugging a USB stick into your PC.

Will my brake lights still work?

Your brake and turn signals will override the flashing pattern. If the module is active and you hit the brakes or use your turn signal, that function will override. This cannot be disabled as it is an important safety feature.

Does this put my vehicle in reverse?

The module will not change your vehicle’s gears. However, some vehicle’s may activate the backup camera screen because they are wired in with the reverse lights. Unfortunately this cannot be disabled at this time.

Will this burn up my bulbs?

Like any headlight/taillight flasher it will burn out your bulbs faster than normal. Aftermarket HIDs will burn up very quickly because the ballasts are not intended to flash

Why are my Halogen bulbs not flashing or very dim?

Unlike LEDs, Halogen bulbs require a charge up and cool down time. Because of this, it is not possible to flash them as fast as LED bulbs.

Is the Z-Flash Plug and Play Flasher for Ford Vehicles traceable?

Once removed, the flasher module does not leave any trace of being installed.
