Prevent Hyperblinking. When you replace incandescent turn signal bulbs with LEDs in most vehicles, the vehicle will start hyperblinking. This is because the LED uses much less power, and the vehicle thinks the bulb is out. You can easily fix this problem by installing resistors. Installation. Each resistor has 6 inch leads for easier installation, and has a rating of 50 watts, 6ohm. This is usually enough to compensate for one bulb. If you are installing four LED turn signals (front and rear), we recommend four total resistors. To install, connect one side of the resistor to the positive turn signal wire, and the other side to negative (ground) with included connectors. To determine which wires to tap on a dual filament socket, we recommend using a voltmeter to test the two power wires. Simply engage your turn signal on the side youre installing the resistor, touch your voltmeter probe to each pin inside of the socket, and the pin that gives a voltage readout is the power wire that needs to be tapped. Typically the ground wire is a black wire. Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting.
