Cadillac CT6 Bulb Size By Years
I started this bulb size chart because I needed a simple, reliable reference for my 2016 Cadillac CT6 and thought of it as a practical mental model for others. At first glance it’s just numbers, but my small win came when matching a replacement for a headlight without trial and error.
As I expanded the list I included common sockets and applications—headlamp, fog, turn signal—to give a clear rule of thumb for choosing bulbs that fit and perform. I refined the entries by testing fitment and brightness so the chart reflects real-world experience and troubleshooting tips that validate the choices.
Quick recap: use the chart to identify the right bulb sizes for your CT6, and shop with confidence. I may earn a small commission if you buy through links on this page, which helps me keep testing and updating resources.
