Wicked Warnings has been around since 2005 with stellar references and we have been using our WAF (Wicked Auto Flasher) module since early 2016 with zero reported vehicle failures. There is no known risk to using any factory lighting as flashers that we are aware of. Of course, all your factory lights will always revert to factory function when the strobes are not being used.
Many of our builds feature a combination of factory lighting as well as purpose-built emergency lights to create a more effective display, so we urge you to consider more than just factory strobe lighting on your build. We have many options available to supplement the factory lighting.
We have 3 connection methods used in our WAF (Wicked Auto Flasher) kits. The way that we manipulate the factory lighting is through the wires. We DO NOT reprogram any of the computers. Everything we do is easily reversible, and any number of individual kits can be combined onto a single switch if desired. There is no single kit to flash all factory lights, as we must retain circuit individuality. The following three methods are used to interface with the factory wires.
We hope this helps to answer any questions about our Auto Flasher Kits and hope you enjoy these products!
