This guide has everything you need to know about the Cadillac CTS headlight assembly upgrade.

Cadillac CTS Headlight History

The first generation of Cadillac CTS was manufactured in 2002 and introduced as a 2003 model. The car was equipped with halogen headlamps and optional high-intensity discharge headlamps. The specs remained the same for many upcoming years. The next update came in 2008, allowing you to replace the standard halogen headlights with xenon lamps.

Fast-forwarding to today, the signature of the Cadillac is a vertical LED light element that has evolved with the headlights. The new models come with projector halogen lamps and optional high-intensity light headlights. 

Of course, there are many aftermarket headlights for low beam and a high beam that are better than stock lights. You can choose LEDs, HIDs, and Xenon headlights depending on your likes and dislikes.
