Buy Cadillac DTS Headlight Assembly

Cadillac DTS Headlight Overview

The Cadillac DTS (DeVille Touring Sedan), produced from 2006 to 2011, features high-intensity discharge (HID) headlights, specifically D1S bulbs, for both high and low beams. These bulbs operate at 35 watts and utilize a PK32d-2 base type. The standard color temperature for these bulbs is approximately 4300K, emitting a bright white light that enhances nighttime visibility. It's important to note that HID bulbs contain trace amounts of mercury and require proper disposal. (AUXITO, O'Reilly Auto Parts)

Over time, the plastic lenses of the headlights can become cloudy or yellowed due to UV exposure and environmental factors. This degradation can significantly reduce light output, making restoration necessary to maintain optimal performance and safety. Restoration methods include wet sanding, polishing, and applying a UV protective coating to the lenses. Professional services or high-quality DIY kits can be used to restore the headlights to their original clarity. (Wikipedia)
