2008 Cadillac CTS V6 DI: Piped light

August 26, 2008

Cadillac CTS Light pipe

I noticed the CTS tail lamps over the weekend for the first time. The press kit calls this lighting element a LED "light pipe" for the rear marker lamp. But for me and a few others here, it looks like an incandescent or fluorescent bulb; LEDs are pretty small. The Engineering Editor said that perhaps there are several LEDs distributed throughout, but the illumination seems too uniform for that. And the Director of Vehicle Testing said the pipe reminded him of this thing. In any event, the light pipe looks good and conveys the vertical styling theme of the tail lamps. Another great styling detail on a sharp car.
