What is the Wicked Warnings Auto Flasher module?

Have you ever wondered how to flash your factory truck lights to turn them into warning or emergency lights? Our Auto Flasher module is the perfect solution. The Wicked Warnings Auto Flasher (WAF) module is a wire-in factory light flasher. The module integrates with your factory lighting and allows you to make factory truck lights strobe.

The module runs on the positive side of a 12-volt electrical system. It lets you isolate and interrupt the factory lighting so you can apply a flash pattern. You can choose from 29 possible flash patterns!

Auto Flasher product highlights:

  • Wire-in module
  • Retains factory light function when flasher is not in use
  • 29 available flash patterns
  • Many different applications and we add new versions regularly
  • “Steady-on” feature for flood and scene lighting
  • Easy installation

How to Install

We’ve separated the Auto Flasher into two sides for convenience. One side of the module features all of the control wires, including:

  • Red wire – Power for flashing
  • White wire – Power for flood
  • Blue wire – Flash pattern adjustment
  • Yellow wire – Synchronization between flashers
  • Black wire – Ground

On the opposite side of the module, there are two channels of input and output. We’ve also created extension cables with color-matched wires to extend from the Auto Flasher to the factory lights that you would like to flash.

The Auto Flasher is a Wicked Warnings exclusive product. You can purchase the module from our online store or our shop in Naperville, IL.

What are the Wicked Auto Flasher Kits & how do they work?

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.

How does the Auto Flasher connect to my truck anyway?

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.

  • Wire Cut: In certain lights, like the white cargo light by the third brake, the only way is to cut a single wire (at this time). We understand that some people are uncomfortable cutting wires and we are working hard to offer “cut-free” solutions as fast as we can. This is how some of the current website kits are sold. Sometimes, this is the only option to achieve the desired display.
  • Wire Swap NO CUT: This is by far our favorite solution and how most of the new generation kits will be made if possible. Wire Swap is how ALL the Headlight and Taillight kits are going to be made for the FORD and many GM trucks. We are working to update the current website options to this new “wire swap” kit and will continue noting any changes on the product online as they happen. It really is just as easy as swapping a wire. Again, the kits will have notes in the description stating which version they are. Click here to watch a video showing the Wire Swap method.
  • (NEW & COMING SOON) Plug N Play Extensions: Plug N Play extensions can be purchased for an extra cost. Please bear with us as these are all handmade and fairly difficult to source parts for. We have some availability and are waiting on some parts for others.

We hope this helps to answer any questions about our Auto Flasher Kits and hope you enjoy these products!
