LIN-4 vs. LIN-6: What’s the Difference

You probably have noticed one of the newest items in our online store, the LIN-6 LED. What you may not know is the LIN-6 is the big brother to the LIN-4, a previously popular Wicked Warnings exclusive. If you are wondering what the differences are between the LIN-6 and LIN-4, continue reading below to find out which LED strobe light you should order today!

LIN-4 vs. LIN-6: Similarities

Both the LIN-4 and LIN-6 are compact units, both 4-in. wide, perfect to fit nearly anywhere you need a warning signal. You can synchronize multiple lights, change flash patterns, or opt for the steady on feature. However, the similarities end there. The LIN-6 is the next-generation LED safety light from Wicked Warnings you need to increase safety and visibility. Check out the differences between the LIN-4 and LIN-6 below.

LIN-4 vs. LIN-6: Differences

If your vehicle has been upfitted with our LIN-4 in the past, you have to bring your rig in to upgrade to the superior LIN-6. The LIN-6 adds two additional LEDs without increasing the size of the unit. This means the LIN-6 is brighter and more visible than ever before. If you thought the LIN-4 was bright, then you should check out the LIN-6, which is over 33% brighter. Key features for the LIN-6 include:

  • 30 flash patterns
  • Simple 5 wire hookup
  • 100% waterproof
  • SAE rated 3 watt LEDs
  • L 5 1/16″ x H 7/8″ x D 11/16 “
  • Steady ON feature included

Video Demonstration of Wire Swap Installation for Auto Flasher Kits - Molex Connector Pin Removal & Replacement

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!
