Left Driver And Right Passenger Side Headlight Set For 03-05 Cadillac DeVille; CAPA Certified

HID stands for "High Intensity Discharge". These bulbs use an electric arc rather than the glowing filament in a Halogen bulb. HID headlamp bulbs do not run on low-voltage DC current like a Halogen Bulb, so they require a ballast, which controls and regulates the flow of current. This ballast will require an ignitor to light the bulb. This is either integrated directly into the bulb or as a separate unit which is occasionally part of the ballast, similar to fluorescent bulbs in your home. In a vehicle, HID bulbs tend to be much more expensive to replace than a Halogen bulb.

Yes we do. Check out our PERDE Xenon and Krypton bulbs while looking up your vehicle. These cast a brighter, white light that reflects well off the road and allows you to see further in the dark. In most cases, these only use 35 to 65 watts. Here at headlightsdepot.com, we offer a limited Lifetime Warranty on perde bulbs. That's how much we believe in this product!

We can provide you with installation instructions if you are unsure of what tools are needed, so please contact us for more information about your specific vehicle and parts you have purchased.
