This is an LED dual conversion harness. This is made by Show Chrome and is designed to allow you to use a standard LED for both running and brake lights or running lights and turn signals. It takes one power lead and reduces the power going to the LED by 50% and leaves the other lead at 100% power. This allows you to have an LED that is on at half brightness while functioning as a running light and then go to full brightness when the brakes or turn signals are applied.  13-307
