Review on 12V LED Flasher by United Pacific: High-Performance with 2 Terminal Design by John Hashman

This is what you need when you are replacing your turn signal bulbs with LEDs AND if you have TWO terminal turn signals to have. Connect the pigtail to ground. Easy. This works much better than building high-current resistors into an LED system. When you install resistors, you essentially negate the entire reason for using LEDs. You want the LEDs to draw little current, but adding a resistor will only simulate a filament load and will draw more current. So you might as well leave the Edison bulbs inside. Get this turn signal if you have a 2 pin turn signal. A MUCH better solution than resistors. Works great with ALL LEDs, partial LEDs, or NO LEDs.
