The signal wires must be connected properly since the LEDs require correct polarity to function. Test the signal & motors before installing the mirror onto the tilt ring since it's VERY difficult to remove intact.

Signal mirrors display a supplemental turn signal through the outside rearview mirror glass surface. The signal is directed toward vehicles in adjacent traffic lanes and is not visible to the driver of the equipped vehicle.

The signal mirrors are equipped with an integrated light sensor and automatically adjust the brightness of the signal display for day and night operation. The signal is connected directly to the turn signal wiring.
