LED Dual Element Circuit

(7 reviews) Write a Review

This LED Dual Element Circuit is necessary (if you aren't using the Motogadget m-Unit) to utilize LED lights as both running lights and brake lights in a simulated dual-filament setup. This circuit moderates low-power and full-power to the LED lighting to intensify the brightness when braking or using turn signals. Pairs with the Flexible Turn and Brake LED Tail Light (8.2" requires 30-60 dual circuit, any longer lengths require 65-125 LED dual element circuits) and the LED Supernova Brake and Turn-Signal Lights (these require 5-10 dual element circuits for up to 2 Supernovas). Simply determine out how many LEDs are used and choose the circuit that will work best for you.

One 5-10 D.E.C. will be sufficient for 1-2 Supernova LEDS. You can use one 15-25 dual element circuit to create a greater variance between the brightness of the Running and Brake Modes, if that's your desired effect.


  • Converts LED lighting to replicate dual-filament incandescent operations
  • A variety of options available to fit your application depending on the number of LEDs used in your lighting setup

    Have used these to wire up minimalist-type lighting for running/turn signals and tail/brake lights. Works great and eliminates some of the head scratching that can happen when trying to set up these little jobs.

    Duality lighting

    This great little pigtail took my trunk lights which are single-element brake light only, and now they act as running AND brake lights. For 7 bucks! Running lights appear about half as bright as brake light - just what I had hoped for. Extremely pleased.

    It does what it says

    What can you say about some inert wire and a diode? If you're trying to use your LEDs for running and stop you need this. It's well made and easy to connect. Works every time.

    Been trying to improve my rear lights on my bike for years. This unit allowed me to use Revival's bright LED's for my brake lights.
