**** Customer experiences with this flasher unit indicate a mixed reception, heavily influenced by compatibility with various types of bulbs. Users commonly report that the installation is straightforward, with many appreciating the plug-and-play nature of the product. For those utilizing incandescent bulbs, the flasher appears to function well, offering a crisp, audible click that enhances the user experience—especially noted in larger vehicle models like trucks. However, issues arise with LED bulb compatibility. While some users find the flasher works successfully with LED indicators, others encounter significant drawbacks, notably the requirement to maintain at least one incandescent bulb per side to achieve proper functionality. This has led to frustrations, particularly among those restoring vintage models or upgrading their lighting systems entirely to LED—all of whom expected compatibility without additional load resistors. Additionally, reports of inConsistent performance were common, with some flashers failing to function correctly either due to blown fuses or malfunctioning units straight out of the package. A lack of clear wiring diagrams and legible labeling on connectors was also a concern for many, making troubleshooting more challenging. In conclusion, while the flasher unit shows potential, especially for traditional setups with incandescent bulbs, its performance with modern LED options leaves much to be desired, leading to a compromise between usability and compatibility across applications. **
