What Lighting System Does the 2019 Buick Cascada Have?

It features an extensive lighting system powered by premium factory HID/Xenon technology utilizing D3S projector housings for high-intensity output.

Can You Put LED Bulbs in a 2019 Buick Cascada?
The 2019 Buick Cascada is already equipped with factory D3S HID/Xenon headlights. Since HID technology already provides exceptional brightness, we recommend staying with high-quality OEM replacement bulbs rather than attempting an LED retrofit for the primary headlights. However, the H11 LED fog lights are typically halogen and are excellent candidates for an LED upgrade to match the color temperature of your HID headlights.
