Novita LM486 Flasher Relay is a direct swap for the factory Trailblazer flasher relay but allows for led bulbs to be used in the marker and brake lights with preventing hyperflash. Without this unit, resistors are needed on each bulb connection to prevent hyperflashing. Use the LM486 for a clean bulb upgrade install!
