Technostalgia 9011 LED Flasher Unit, 5-Prong

Generally, a conventional turn signal flasher will continue to work with our LED taillights as long as there is a full sized (i.e. 1157) bulb in the front turn signals. If your car has tiny bulbs in the front turn signals, LED front turn signals, or no front turn signals at all, you will need this grounded turn signal flasher designed specifically for LEDs.
