The Signal Mirror® kit that retrofits the CTS is #220-0326-H with the suggested retail price of $269. The kit also can be to work with the turn indicators or with turn and brake lights. Or you can add the Multi-Function Module that adds other enhancements to the Signal® Mirrors. Professional installation is recommended.

A high-intensity red or amber chevron flashes through-the-glass™ of Signal® Mirrors when a turn indicator is activated. The chevron alerts surrounding drivers in the “blind spots” of the vehicle. When hazard flashers are used chevrons flash in both mirrors. The mirrors function as regular mirrors whether the turn signals or hazard flashers are on or off. Unlike the adjacent drivers who see a highly visible lighted display, the driver of the CTS equipped with Signal® Mirrors sees a subtle tell-tale display.

This year, Motor Trend selected the CTS as the 2008 Car of the Year for its smart restyling. “For that remarkable achievement, and for making us grin like lottery winners every time we drove it, the CTS is our enthusiastic choice for Motor Trend’s 2008 Car of the Year,” the magazine reports. Motor Trend has also called Signal® Mirrors, “way cool.”
