If you’re wondering how to make factory truck lights strobe, you’re in the right place!

What is the Auto Flasher Module?

The Auto Flasher module is a dual-channel, fully isolated flash module that completely interrupts the factory circuit to make factory truck lights strobe. The module 100% protects and isolates the vehicle’s sensitive computer parts, and factory light functionality will work as usual when the module is not activated.

The module will not “flash all of the lights at once” as it only flashes the lights described in each kit. For example, a Reverse Lights Auto Flasher Kit will only make a set of factory LED reverse lights strobe. If you would like to also make your factory cargo lights strobe, you would need a second kit. You can use multiple kits on one vehicle, and multiple kits are required to flash more than one set of factory lights.

No other product allows the lighting displays you can achieve with the Auto Flasher Module. The module has 29 flash patterns and also features the popular steady burn option that you can use to illuminate lights for working or loading. We use a waterproof casing around the module so you can mount it indoors or outdoors on your vehicle.

How Does it Connect to my Vehicle?

We have 3 different connection methods for our Auto Flasher Kits. The connection methods refer to the way we manipulate the factory lighting through the wires. We DO NOT reprogram the computers.

Wire-Cut Kit

For certain factory lights, such as the white cargo light by the third brake light, the only way to create a strobe light is to cut a single wire (at this time). Sometimes, this is the only option to achieve the desired display.

Wire Swap Kit

The wire swap method is our favorite solution and how we will make most of our new kits if possible. This method is just as easy as swapping a wire, and you will NOT have to cut any wires for installation.

Plug N Play

PNP extensions are coming soon! We will update the website as more plug-and-play extensions become available. Some are ready now. If interested, please email us.

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!
