Note: We ask that you carefully review vehicle compatibility and other product/install information before making your purchase. Help us reduce the possibility of returns as much as possible and reduce the carbon footprint of our products.

We have a 90-day manufacturer's warranty against defects from the manufacturing process. This covers issues that prevent the proper installation or performance of the product. Warranty is valid only when accompanied by valid proof of purchase. The purchase must be made directly from an authorized retailer or the manufacturer’s official store. Purchases made through third-party sellers, marketplaces, or unauthorized resellers will not be eligible for warranty coverage. To be eligible for warranty claims, the original purchase receipt or other proof of purchase must be provided. Without such proof, warranty claims may be denied by Miller CAT.

Cosmetic imperfections that occur either from the manufacturing or shipping process are not covered. We do not manufacture cosmetic products or ones designed for show.

We do NOT guarantee our product against theft. The Ford F-Series Security Screws are a deterrence device that are meant to discourage theft and/or make it more difficult for thieves to steal your tail lights. Given the right tools, technique or time, a thief can still take your tail lights. However, by installing our security screws, you are significantly increasing your protection against theft. Similar to a car or home alarm, you are making thieves second-guess themselves and consider moving onto another target.

Miller CAT is not liable for any consequential damages arising from the use of this product, including but not limited to labor costs, transportation costs, damage to other parts of the vehicle, or damage to persons, other property or vehicles.
