Expanded Benefits

No More Hyperflash or Compatibility Problems
Standard flashers aren’t designed for low-draw LEDs. This LED-safe flasher ensures your signals blink at the correct rate, regardless of LED load.

Some vehicles and LED housings reverse the polarity, causing lights not to function. The included polarity reversing adapter solves this immediately—no rewiring required.

Suitable for most vehicles running LED turn signals, tail lights, and side markers on a 12V DC electrical system. Works on classic cars, trucks, hot rods, and custom builds requiring an updated flasher system.
