Diode Dynamics LED Flasher Relays

Diode Dynamics LED flasher relays are ideal solutions if you're converting to newer LED lights. When your factory turn signal bulbs go out, your vehicle's flasher senses that power loss, and it will blink the turn signals quickly to alert you. Since LED bulbs use less power, you get the same fast blinking (a. k. a. "hyperblinking"). So even though the LEDs are functioning just fine, your car thinks the bulbs went out! Regulate those no-flashing or fast-flashing issues with the Diode Dynamics LED flasher relays designed to fit your application.
