Flash your factory GMC Sierra 2500 and up Headlight DRL (C-Rings) with the Auto Flasher module! This Auto Flasher Kit will work for 2015-2019 Sierra 2500-3500 trucks with factory LED lighting. LED lights are best to use with this product as they flash the fastest and have the greatest response. We do not recommend using this on a NON-LED vehicle.
When you purchase an Auto Flasher Kit, you will receive all needed wire to complete the task and often a link to an installation video as well. Our instructions are constantly evolving as we improve the product so please have some patience.
The Auto Flasher module is extremely versatile and can flash the factory lights on your vehicle. This product DOES NOT flash “all the lights at once”, it only flashes the lights in the kit you purchased. 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. This dual-channel, fully isolated flash module completely interrupts the factory circuit to vehicle lights, and 100% protects and isolates the vehicle’s sensitive computer parts. When the Auto Flasher is not activated, factory light functionality will work as usual.
This module includes 29 flash patterns and also features our popular steady burn option that can be used to illuminate reverse or other lights for loading or working. This product also features a waterproof casing, and it is completely self-contained. You can mount the module indoors or outdoors on your vehicle. We are working very hard to offer vehicle-specific connectors for this soon. Make sure you sign up for the newsletter to be the first to know.
**Please Note: We do NOT recommend using this module with your brake lights. At Wicked, we firmly believe that brakes should stay brakes.
Please read the instruction guide, and view our demo video. Our demo video will provide more detail about the typical installation of the Auto Flasher by showing how we can hook it up to 2 lights on the benchtop. The video also displays the available flash patterns and shows you how to wire the module correctly. This is just a DEMO video, and not a step by step vehicle specific video like you receive when you purchase a kit.
We encourage our customers to PLEASE ask for assistance if you are unsure. This is NOT a product to go guessing with, or vehicle damage may result. We strongly recommend a 12v digital voltmeter for these installations, not just a basic test light. If you have any questions about installing this product, please send us an email at firstname.lastname@example.org.
