Headlights Not Flashing?

If your headlights are not flashing on your Z-Flash please make sure that your vehicle's headlights are not on or set to automatic. If your headlights are on then it will override the Z-Flash just like how when you engage the Brakes and Turn Signals it overrides the module from flashing as a safety feature.
