Cadillac has already been releasing a steady drip of information about what's going into its 2013 XTS like its autonomous-vehicle tech, and now it's focusing on lighting choreography. Cadillac reminds us that its lighting signature is vertical bands of illumination, tying it back to 1948, when the tailfins for which the brand is still known were first used on cars like the Fleetwood Sixty Special and Series 61 Coupe.
Traffic lights using state-of-the-art LED illumination use 90 percent less electricity, offer a much longer service life and are more durable than their incandescent counterparts. Taking advantage of the countless benefits, cities around the country have been replacing traditional filament-based traffic signal bulbs with LEDs for years. Unfortunately, the low-watt LED units burn much cooler than its white-hot counterpart making it unable to melt snow off weather exposed traffic fixtures.
