The Profile FlashPack Relays offer a reliable solution to hyperflash issues in automotive LED lighting. These high-quality relays, designed in collaboration with industry experts, replace the existing flasher relay in your vehicle's circuit, ensuring stable and efficient LED performance. Unlike traditional band-aid fixes using wire taps and resistors, the FlashPack Relays provide a permanent, no-modification-required solution. The circuitry compensates for hyperflash, allowing your turn signals to blink at a normal rate. Installation is hassle-free, making it a convenient plug-and-play choice. These relays are compatible with many GMC/Chevy vehicles, but we recommend verifying compatibility with your specific model for a seamless upgrade.
