Folany Relays Editorial Review

The 1Set H4 Relay Harness has garnered mixed reviews from customers, primarily revolving around its functionality and ease of installation. Users have reported that the product fulfills its intended purpose effectively, allowing for enhanced headlight performance. Many appreciate the convenience of a ready-made wiring loom, noting that it simplifies the installation process significantly compared to creating a custom setup. However, some users have pointed out a critical limitation of the harness: it does not accommodate vehicles with a switched ground configuration. This oversight can lead to compatibility issues for certain vehicles, indicating that Prospective buyers should carefully review their vehicle's wiring before purchasing. Overall, the product is seen as a practical option for many, especially for those looking for an easy installation without the hassle of making up their own wiring. ###
