Here at MADNESS Autoworks, family is always at the center of our core values.
As the COVID-19 (coronavirus) situation unfolds we want to let you know we are committed to the physical, emotional and financial health of our family - including employees, customers, ambassadors, vendors and industry partners.
As you are likely aware, the World Health Organization recently classified the global outbreak of COVID-19 (coronavirus) as a global pandemic. This has caused the government at all levels across the country to take drastic measures many of us have never experienced.
We plan to continue serving our community and fellow enthusiasts by quickly adapting to the rapidly changing situation and minimize the impact on our family.
We will continue to fulfill your orders as quickly and safely as possible, service and customize your vehicles in-house and provide you with online or over the phone customer service / support.

We offer the best products at the best price available on every item in our store. All prices are listed in U.S. dollars. Orders placed with us will be charged in U.S. dollars. If you live outside the U.S., this charge is converted by your bank into your local currency and should appear on your credit card statement in that currency.
We will match the published price of any US supplier* -- even their current sales prices! If you find an item advertised at a lower price, make a notation in your online order, call or email us at email@example.com with your price match request (see terms and details below). We'll sell you the SAME item at the SAME price! If you've already purchased the item from us, we'll even price match (for store credit only) as long as you contact us with your request within 7 days of placing your order.
This offer is restricted to identical items offered for sale in writing or on the web. When making your price match request, you must provide us with a link to the competitor's Internet URL for the item, a copy of the written ad or written quotation, which must include Supplier's part number, description and price.
Price Match Terms and Fine Print:
In some cases we may choose not to price match; here are some reasons why:
• The competitor's product is not an exact match (identical manufacturer & model) with ours.
• The competitor with the lower price does not have the item in stock at their warehouse.
• The competitor's total price (including shipping, handling, taxes, etc.) is higher.
• The competitor's product is used, refurbished, reconditioned, or a display model.
• The competitor is not selling in US dollars.
• The product is a clearance or closeout item.
• The item is not found within the first 10 items listed on major search engine results.
• The competitor is not manufacturer authorized or has advertised below the manufacturers minimum allowed price for the item.
* Qualified U.S. Suppliers are established businesses that routinely and regularly sell the item to be matched from an established physical storefront or warehouse.
While we endlessly aim to maintain the accuracy of item availability, descriptions and availability, we reserve the right to correct errors. We reserve the right to choose not to honor this offer.
How to Request a Price Match:
Please send a separate email with the subject header of PRICE MATCH REQUEST. Provide the competitor's name, part number, item description, URL link to the exact item and the competitor's price along with your request to price match. If we agree to match the price, you will be contacted with a confirmation and directions on how to place your order for the price request. In the event we cannot match the price, we will notify you by email.
Alternatively, you may call us with your request. We'd love to talk with you. We generally respond to price match requests within one business day.
The RGB function allows for full multicolor control using any standard RGB controller, to accent the look of your Sierra and make it stand out on the road.
The GMC Sierra has two LED accent bars in the headlights. They are illuminated by circuit boards that hold white LEDs. Our replacement LED boards utilize RGBW LEDs instead! The RGB function allows for full multicolor control using any standard RGB controller, to accent the look of your Sierra and make it stand out on the road.
This product is not just RGB though- it is RGBW! That means there is an LED chip that is specifically white in color, right next to the standard red, green, and blue chips. By using an RGBW controller rather than the standard RGB, you can activate and control the white chip independently of the colors. This provides a much more uniform, pure, and bright white color than the traditional method of combining all RGB signals, so you can keep a clean, factory white appearance for everyday driving. With this setup, both LED bars will be on at the same time, instead of just one or the other.
You don't have to align and fasten LEDs by hand- this is an OEM-grade solution, with exact fitment, and perfect alignment of the new LEDs. Just remove the factory boards, and ours fit directly in place. Your order includes two sets of LED boards, one for each side.
To drive the high-power LEDs safely, a new constant-current, waterproof, inductive driver is included for each set. You will also need a standard RGB or RGBW controller. Controllers can usually be powered by any standard 12V source. We recommend connecting to the parking light signal, so this module lights up when the parking lights or headlights are on. Remember, when you're not showing off, you can set the LEDs to pure white for everyday use.
Professional installation is strongly recommended, as the factory headlights must be opened in order to replace the LED panels. Wiring instructions are included to identify the wire colors required to power your controller.
