This pair of directional mirrors from Classic Design Concepts have an LED directional arrow embedded within the mirror's frame to add unique style and an additional safety precaution to your 2005 to 2009 Mustang. The mirror does not require modification of the mirror housing.
The LEDs activate when the turn signal comes on and helps to warn other drivers about your impending move. CDC's kit involves removing the the stock mirror and installing their LED mirror. Power is brought to the mirror from inside the Mustang with the provided wiring. CDC includes installation hardware and instructions.
